MODIS Collection 6 Liquid cloud bulk optical properties
No full textThis database provides liquid cloud bulk optical properties computed using the water refractive indices and droplet size distributions assumed in the Moderate resolution spectroradiometer (MODIS) Collection 6 cloud retrieval algorithm. The database covers 470 wavelengths ranging from 0.02 to 200 µm. Cloud effective radii range from 2 to 30 µm in 1 µm increments. Droplet single scattering properties at 1e4 droplet diameter values logarithmically distributed between 1e-3 and 1e3 µm are computed with the Lorenz-Mie code. The single scattering properties are subsequently integrated over the droplet size distributions to obtain the bulk optical properties
Radar Classification of the Antarctic Ice-Bed Interface: Version 2
No full textThis classified_bed data product represents the radar bed classification shown in Young et al., 2016. Values of 0 represent specularity content below 20%; values of 3.3 represent specularity content above 20% and energy 1 microsecond below the bed 15 dB lower than the bed echo, and values of 6.7 represent specularity content above 20% and energy 1 microsecond below the bed 15 dB within than the bed echo. Grids for specularity content and post bed echo are also available. Data is available as COARDS-compliant netCDF-4/HDF5 grids (.grd) and GeoTiffs (.tiff), both in EPSG 3031 (Antarctic Polar Stereographic) projection.
Data were gridded using GMT6.1 and the nnbathy natural neighbor interpolator. Cell size was 1 km, gaussian filter distance was 5 km, and mask radius was 2 km.
Browse images, with Bedmap3 (Pritchard et al., 2025) surface elevation contours and MEASURES phase derived surface velocities (Mouginot et al. 2019) are available for each dataset.
An interpretation of the values in the classified_bed product is that low values are rough bed, intermediate values are isotropic wet bed, and high values are anisotropic wet bed.
Version 1 includes data from the 2016 paper, including AGASEA over Thwaites Glacier (Holt et al., 2006), ATRS over West Antarctica (Peters et al., 2005), GIMBLE over Marie Byrd Land (Young et al, 2013) and parts of ICECAP over Wilkes Subglacial Basin, Dome C, Highland B and Totten Glacier. (Young et al, 2011, Young et al., 2016). We expect updates to the coverage as part of work funded by the Arête Glaciers Initiative.

Cartas episcopales que proponen dividir varias parroquias grandes en Puebla, 1772 octubre 17-1773 marzo 15
No full textCartas del obispo de Puebla al virrey Antonio María de Bucareli proponiendo la división de varias parroquias grandes en la diócesis de Puebla. El obispo sostiene que las largas distancias, el terreno difícil y el elevado número de feligreses impiden una adecuada administración espiritual, en particular para las comunidades indígenas que con frecuencia morían sin sacramentos o no podían asistir a misa. Recomienda la creación de nuevos curatos en lugares como San Mateo, Xicochimalco, Xochioloco, San Juan Tzicatlacoyan, Cuyoaco y Amatlán para garantizar una mejor atención pastoral. —— Letters from the Bishop of Puebla to Viceroy Antonio María de Bucareli proposing to divide several large parishes in the Diocese of Puebla. The bishop argues that long distances, difficult terrain, and the high number of parishioners prevent proper spiritual administration, particularly for Indigenous communities who often died without sacraments or could not attend Mass. He recommends the creation of new curates in places such as San Mateo, Xicochimalco, Xochioloco, San Juan Tzicatlacoyan, Cuyoaco, and Amatlán to ensure better pastoral care. 12 f. (24 p.

Data Archive for: "Exploring 3D Landscapes Across the Solar System" Outreach Activity
No full textThis archive contains data associated with an outreach activity to look at 3D landscapes on Earth and Mars, initially designed by Tim Goudge (The University of Texas at Austin) for STEM Girl Day at UT Austin (https://girlday.utexas.edu/). This activity challenges K-8th grade students to match 3D printed models with 2D images of the same landscapes. This archive contains all the digital materials necessary to replicate this outreach activity, which is further described in the following abstract: Goudge, T. A., M. D. Nelson, L. Turner, J. Gulick, E. Cote, E. C. Hiatt, R. D. Moore, and M. A. Carrington (2025), Planetary Surface Exploration Teaching and Outreach with Uncrewed Aerial Vehicles, 56th Lunar and Planetary Science Conference, Abstract 1367. Please feel free to use these data to recreate this activity for your own outreach event!! If you do so, I (Tim Goudge) would love to hear from you about how it goes
