A first global height-resolved cloud condensation nuclei data set derived from spaceborne lidar measurements
No full textWe present a global multiyear height-resolved data set of aerosol-type-specific cloud condensation nuclei concentrations (nCCN) estimated from the spaceborne lidar aboard the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite. For estimating nCCN, we apply the recently introduced Optical Modelling of the CALIPSO Aerosol Microphysics (OMCAM) algorithm to the CALIPSO Level 2 Aerosol Profile product. The estimated nCCN are then gridded into a uniform latitude–longitude grid of 2∘×5∘, a vertical grid of resolution 60 m from the surface to an altitude of 8 km, and a temporal resolution of 1 month. The data span a total of 186 months, from June 2006 to December 2021. In addition, we provide a 3D aerosol-type-specific climatology of nCCN produced using the complete time series. We further highlight some potential applications of the data set in the context of aerosol–cloud interactions. The complete data set can be accessed at https://doi.org/10.1594/PANGAEA.956215 (Choudhury and Tesche, 2023).</p

Global multiyear 3D dataset of cloud condensation nuclei derived from spaceborne lidar measurements
No full textWe present a novel multiyear global dataset of height-resolved number concentrations of cloud condensation nuclei (NCCN) at a supersaturation of 0.20 %. The NCCN is estimated from the spaceborne CALIPSO (Cloud-Aerosol Lidar and Infra-Red Pathfinder Satellite Observation) lidar measurements using the OMCAM (Optical Modeling of CALIPSO Aerosol Microphysics) algorithm. The data also includes aerosol-type-specific NCCN for five aerosol types: dust, marine, polluted continental, elevated smoke, and clean continental. It has a monthly resolution, covering the time period from June 2006 to December 2021. We further provide a 3D climatology of aerosol-type-specific NCCN estimated from the complete time series. Data are provided as yearly netCDF files (netCDF version 4), given at a horizontal latitude-longitude grid of 2° × 5° and a vertical resolution of 60 m
Solar radiative effects of non-spherical mineral dust particles during SAMUM 2006
No full textDuring the SAMUM campaign comprehensive measurements were performed in May-June 2006 concerning the physico-chemical and radiative properties of Saharan mineral dust. Based on these observations optical properties for a dust plume were calculated using measured number size distributions as well as information on the particles’ chemical composition and predominant shape. For a wavelength of 550 nm size-resolved complex refractive indices of 1.5-1.58 and 0.004-0.005 were derived for the real and imaginary part, respectively. For 550 nm the single scattering albedo and the asymmetry parameter of the phase function attained values of about 0.8, so that the SAMUM Saharan mineral dust appears to be absorbing and forward scattering. In addition, a considerable impact on the optical properties can be traced back to the presence of coarse dust particles.
Mie simulated backscatter coefficients and lidar ratios were not in agreement with independent data measured by various lidars confirming that the observed Saharan mineral dust particles had non-spherical shapes. The lidar measurements provided key-information to quantify the predominant shape of the particles. Assuming spheroidal model particles comprehensive simulations demonstrated that a mean oblate shape (axis ratio, AR, of about 1:1.6) led to the best agreement with the lidar data. This was confirmed by single particle analyses using a scanning electron microscope, too.
For the purpose of extensive radiative transfer simulations for ensembles with non-spherical particles, a comprehensive database of optical properties for single oblate and prolate spheroidal particles was built up. Our computations show significant non-sphericity effects of the observed dust: For oblate particles (AR 1:1.6) the single scattering albedo is weakly affected by only 1, but the asymmetry parameter is reduced by important 4%. Assumptions on how to interpret particle ‘size’ and ‘shape’ may cause positive and negative changes for all optical properties. The spectral optical depths for extinction and scattering may vary by +/-7% as a function of the particular size-shape equivalence relation adopted.
The downward radiative transport is simulated to be less influenced by the particles’ non-sphericity. On the other hand, reflectance is predominantly forced, i.e. non-spherical particles enhance the population’s backscattering. For example, for SAMUM conditions and for the wavelength range 0.3-2.2 nm, the top-of-atmosphere local radiative forcing over a non-reflecting surface increases from 6 W/m² (spheres) to 16 W/m² (oblate spheroids, AR 1:1.6). These and other issues of non-spherical dust particles during SAMUM will be discussed
Regional dust model performance during SAMUM 2006
No full textTraditionally there has been a lack of intensive measurements directly over dust sources for validating the accuracy of dust models. Utilizing the valuable and unprecedented SAMUM 2006 field campaign dust dataset in North Africa, we assess the performance and discuss the limitations of a state-of-the-art dust regional model to reproduce the complex dust patterns encountered during the campaign. The DREAM model operational forecast version during SAMUM 2006 (OPER) and an updated model version (RESH) are run and compared. RESH reproduces the general Saharan dust pattern, whereas OPER shows limitations to quantitatively reproduce dust optical properties over sources and after long range transport simultaneously. Dust transport in RESH with enhanced number size bin distribution is proven to be more efficient and adequate. The modeled vertical extinction coefficient captures fairly well lidar observations. While particle number size distribution is consistently reproduced at surface level, we find significant underestimation in the middle troposphere for large particles. Occasionally, synoptic scale meteorology remains unsatisfactorily captured leading to errors in the location and intensity of dust emission and subsequent transport. Citation: Haustein, K., C.

Music Theatre as Labyrinth. Extension of liminality in the production The Navidson Records by Till Wyler von Ballmoos and Tassilo Tesche
No full textFor the 2016 edition of the ‘Münchener Biennale – Festival für Neues Musiktheater’ (Munich Biennale – Festival for New Music Theatre), its new Intendants Daniel Ott and Manos organised a series of preparatory workshops intended to promote the creation of new works. This essay explains the influence that this new form of curating process exerted on the gestation of the production The Navidson Records by Till Wyler von Ballmoos and Tassilo Tesche. Our focus is on investigating the working methods employed in the process of conception and rehearsal: the setting of The Navidson Records was from the start intended to avoid creating fixed performance procedures and instead to create an open space of potential. The author analyses the characteristics of that space with the aid of hypotheses derived from ritual theory. A central role here is played by the concept of liminality, which Victor Turner uses to describe the ritual borderline phase between two stable states. This article demonstrates the tendency of current composed theatre to undermine normative patterns of roles and organisation by means of strategies of liminalization. The potential and the difficulties inherent in participant observation in a creative work process are also discussed here

Dust and smoke transport from Africa to South America : Lidar profiling over Cape Verde and the Amazon rainforest
No full textQuasi-simultaneous vertically resolved multiwavelength aerosol Raman lidar observations were conducted in the near field (Praia, Cape Verde, 15 degrees N, 23.5 degrees W) and in the far field (Manaus, Amazon basin, Brazil, 2.5 degrees S, 60 degrees W) of the long-range transport regime between West Africa and South America. Based on a unique data set (case study) of spectrally resolved backscatter and extinction coefficients, and of the depolarization ratio a detailed characterization of aerosol properties, vertical stratification, mixing, and aging behavior during the long-distance travel in February 2008 (dry season in western Africa, wet season in the Amazon basin) is presented. While highly stratified aerosol layers of dust and smoke up to 5.5 km height were found close to Africa, the aerosol over Manaus was almost well-mixed, reached up to 3.5 km, and mainly consisted of aged biomass burning smoke.
