However, data sets that originate from real networks are rare. Network data is considered privacy-sensitive, and the purposeful introduction of malicious traffic is usually not possible.</p> <p>In this paper, we introduce a labeled data set captured at a smart factory located in Vienna, Austria, during normal operation and during penetration tests with different attack types. The data set contains 173 GB of PCAP files, representing 16 days (395 hours) of factory operation. It includes MQTT, OPC UA, and Modbus/TCP traffic.</p> <p>The captured malicious traffic originated from a professional penetration tester who performed two types of attacks:<br>(a) Aggressive attacks that are easier to detect.<br>(b) Stealthy attacks that are harder to detect.</p> <p>Our data set includes the raw PCAP files and extracted flow data. Labels for packets and flows indicate whether they originated from a specific attack or from benign communication. </p> <p>We describe the methodology for creating the dataset, conduct an analysis of the data, and provide detailed information about the recorded traffic itself. The dataset is freely available to support reproducible research and the comparability of results in the area of intrusion detection in industrial networks.</p> <p> </p> <h3>Technical details</h3> <ul> <li>readme.txt <ul> <li>Information about the data collection, format, necessary software and versions to access it.</li> </ul> </li> <li>license.txt: <ul> <li>Licensing information.</li> </ul> </li> <li>a_day1, a_day2, s_day1, s_day2, tf_a, and tf_s: <ul> <li>  Main dataset, where files starting with "tf" are training files containing only benign, <br>  operational data.

This method proceeds entirely under ball milling conditions without the requirement of any solvent while eliminating the need for intermediate purification. Careful optimization of the milling parameters and reagent addition enables efficient conversion of various α,β-unsaturated aldehydes and ketones with electron-deficient dienophiles to the corresponding cycloadducts via diene intermediates, demonstrating high stereoselectivity and yielding exclusively endo Diels-Alder adducts. Furthermore, the extension of the sequence by a solvent-free one-pot oxidation is exemplified, achieving a three-step synthesis in a single milling vessel without intermediate workup and purification, which exhibits excellent green metrics in comparison with solution-based methods. This operationally simple and sustainable approach demonstrates the potential of mechanochemistry to streamline multistep organic synthesis, while reducing solvent use and energy demand.</p> <p>The publication and its Supplementary Information can be found as open-access files on the publisher's website (see DOI).</p> <p>All files containing the analytical raw data for all compounds given in the Supplementary Information of the manuscript are uploaded. An additional file named<strong><em> RSC_Mechanochem_2025-compound_list.pdf </em></strong>is uploaded, that should clearly link the compound number given in the paper to the respective entry in the ELN (nbiederm) and the respective analytical data file.</p> <h3>Technical details</h3> <p>The files uploaded contain the FIDs of NMR spectra recorded by an in-house Bruker Spectrometer. Standard software (such as <a href="https://mestrelab.com/download/mnova/">MestreNova</a> or <a href="https://www.bruker.com/en/products-and-solutions/mr/nmr-software/topspin.html">Topspin</a>) is required to display NMR spectra.</p&gt

    &lt;p&gt;This dataset was produced with funding from the European Space Agency (ESA) Climate Change Initiative (CCI) Plus Soil Moisture Project (CCN 4 to ESRIN Contract No: 4000126684/19/I-NB "ESA CCI+ Phase 1 New R&amp;D on CCI ECVS Soil Moisture").&nbsp; Project website: &lt;a title="ESA CCI SM website" href="https://climate.esa.int/en/projects/soil-moisture/" target="_blank" rel="noopener"&gt;https://climate.esa.int/en/projects/soil-moisture/&lt;/a&gt;&lt;/p&gt; &lt;p&gt;This dataset contains information on the Surface Soil Moisture (SM) content derived from satellite observations in the microwave domain.&lt;/p&gt; &lt;h2&gt;Abstract&lt;/h2&gt; &lt;p&gt;The ESA CCI Soil Moisture medium-resolution (MR) science product provides soil moisture at a finer spatial resolution of 0.1&deg; x 0.1&deg;. The MR product delivers COMBINED SSM data for the time period 2002-2024. The production of the MR product follows the same methodology as the main CCI product, with adaptations introduced to account for the higher resolution. A key objective of the MR product is to better capture mesoscale SSM patterns, because the variability at these scales plays an important role in triggering convective storms through land&ndash;atmosphere interactions (Chug, 2023). Particularly, SSM contrasts over distances of 10 to 40 km have a strong influence on the initiation of mesoscale convective systems (MCSs) in the Sahel (Taylor, 2011), where such systems account for most of the annual rainfall (Mathon, 2002). The main CCI product at 0.25&deg; resolution has proven to be too coarse for resolving the land surface features to convective system initiations.&lt;/p&gt; &lt;h3&gt;Summary&lt;/h3&gt; &lt;ul&gt; &lt;li&gt;Daily global estimates of volumetric surface soil moisture from 2002-2024 at 0.1&deg; resolution&lt;/li&gt; &lt;li&gt;Based on a selection of active (ASCAT) and passive sensors (AMSR-E, AMSR-2, GMI, FengYun, SMOS and SMAP).&lt;/li&gt; &lt;li&gt;0.1&deg; resolution obtained using a nearest neighbour resampling (passive) or a two-dimensional Hamming window approach (active)&lt;/li&gt; &lt;li&gt;For more information see: ATBD (link coming soon..)&nbsp;&lt;/li&gt; &lt;/ul&gt; &lt;h2&gt;Programmatic (bulk) download&lt;/h2&gt; &lt;p&gt;You can use command-line tools such as&nbsp;&lt;a href="https://www.gnu.org/software/wget/" target="_blank" rel="noopener"&gt;wget&lt;/a&gt;&nbsp;or&nbsp;&lt;a href="https://curl.se/" target="_blank" rel="noopener"&gt;curl&lt;/a&gt;&nbsp;to download (and extract) data for multiple years.

As a result, the wrong interpolation algorithm (DCT-PLS vs linear interpolation) may be used&nbsp;for the misclassified regions in the gap-filling process (linear interpolation is used for frozen conditions). This affects only regions where in a 5x5 degree region both frozen and unfrozen soil conditions appeared. Spatial subsets, where all locations are frozen or non-frozen, are not affected. Other years (before 2024) are not affected. Please contact us if you require more information.&lt;/p&gt; &lt;h2&gt;Abstract&lt;/h2&gt; &lt;p&gt;ESA CCI Soil Moisture is a multi-satellite climate data record that consists of harmonized, daily observations coming from 19 satellites (as of v9) operating in the microwave domain. The wealth of satellite information, particularly over the last decade, facilitates the creation of a data record with the highest possible data consistency and coverage.&lt;br&gt;However, data gaps are still found in the record. This is particularly notable in earlier periods when a limited number of satellites were in operation, but can also arise from various retrieval issues, such as frozen soils, dense vegetation, and radio frequency interference (RFI). These data gaps present a challenge for many users, as they have the potential to obscure relevant events within a study area or are incompatible with (machine learning) software that often relies on gap-free inputs.&lt;br&gt;Since the requirement of a gap-free ESA CCI SM product was identified, various studies have demonstrated the suitability of different statistical methods to achieve this goal. A fundamental feature of such gap-filling method is to rely only on the original observational record, without need for ancillary variable or model-based information. Due to the intrinsic challenge, there was until present no global, long-term univariate gap-filled product available. In this version of the record, data gaps due to missing satellite overpasses and invalid measurements are filled using the Discrete Cosine Transform (DCT) Penalized Least Squares (PLS) algorithm (Garcia, 2010). A linear interpolation is applied over periods of (potentially) frozen soils with little to no variability in (frozen) soil moisture content. Uncertainty estimates are based on models calibrated in experiments to fill satellite-like gaps introduced to GLDAS Noah reanalysis soil moisture (Rodell et al., 2004), and consider the gap size and local vegetation conditions as parameters that affect the gapfilling performance.&lt;/p&gt; &lt;h3&gt;Summary&lt;/h3&gt; &lt;ul&gt; &lt;li&gt;Gap-filled global estimates of volumetric surface soil moisture from 1979-2024 at 0.25&deg; sampling&lt;/li&gt; &lt;li&gt;Fields of application (partial): climate variability and change, land-atmosphere interactions, global biogeochemical cycles and ecology, hydrological and land surface modelling, drought applications, and meteorology&lt;/li&gt; &lt;li&gt;Method: Modified version of DCT-PLS (Garcia, 2010) interpolation/smoothing algorithm, linear interpolation over periods of frozen soils.

The file name has the following convention:&lt;/p&gt; &lt;blockquote&gt; &lt;p&gt;ESACCI-SOILMOISTURE-L3S-SSMV-COMBINED_GAPFILLED-YYYYMMDD000000-fv09.2.nc&lt;/p&gt; &lt;/blockquote&gt; &lt;h3&gt;Data Variables&lt;/h3&gt; &lt;p&gt;Each netCDF file contains 3 coordinate variables (WGS84 longitude, latitude and time stamp), as well as the following data variables:&lt;/p&gt; &lt;ul&gt; &lt;li&gt;&lt;strong&gt;sm&lt;/strong&gt;: (float) The Soil Moisture variable reflects estimates of daily average volumetric soil moisture content (m3/m3) in the soil surface layer (~0-5 cm) over a whole grid cell (0.25 degree).&lt;/li&gt; &lt;li&gt;&lt;strong&gt;sm_uncertainty&lt;/strong&gt;: (float) The Soil Moisture Uncertainty variable reflects the uncertainty (random error) of the original satellite observations and of the predictions used to fill observation data gaps.&lt;/li&gt; &lt;li&gt;&lt;strong&gt;sm_original&lt;/strong&gt;: Original measurements (with observation gaps) before gap-filling.&lt;/li&gt; &lt;li&gt;&lt;strong&gt;sm_smoothed&lt;/strong&gt;: Contains DCT-PLS predictions used to fill data gaps in the original soil moisture field. These values are also provided for cases where an observation was initially available (compare `gapmask`). In this case, they provided a smoothed version of the original data.&lt;/li&gt; &lt;li&gt;&lt;strong&gt;gapmask&lt;/strong&gt;: (0 | 1) Indicates grid cells where a satellite observation is available (1), and where the interpolated (smoothed) values are used instead (0) in the 'sm' field.&lt;/li&gt; &lt;li&gt;&lt;strong&gt;frozenmask&lt;/strong&gt;: (0 | 1) Indicates grid cells where ERA5 soil temperature is &lt;0 &deg;C. In this case, a linear interpolation over time is applied.&lt;/li&gt; &lt;/ul&gt; &lt;p&gt;Additional information for each variable is given in the netCDF attributes.&lt;/p&gt; &lt;h3&gt;Version Changelog&lt;/h3&gt; &lt;p&gt;Changes in &lt;em&gt;v9.2&lt;/em&gt;&nbsp;(previous version was &lt;em&gt;v09.1r1&lt;/em&gt;):&lt;/p&gt; &lt;ul&gt; &lt;li&gt;Now based on the v9.2 COMBINED product&lt;/li&gt; &lt;li&gt;Years 1979 to 1990, and 2024 are now included as&nbsp;well&lt;/li&gt; &lt;li&gt;Algorithm is the same as described in Preimesberger et al.
