Historical MODIS/Terra L3 Global Daily 500m SIN Grid Snow Cover, Snow Albedo, and Snow Physical Properties, Version 1
This data set represents a spatially and temporally complete (STC) version of the MODIS Snow Covered Area and Grain-size (MODSCAG) and MODIS Dust Radiative Forcing in Snow (MODDRFS) data sets produced by the NASA Jet Propulsion Laboratory (JPL) and now produced and distributed by NSIDC DAAC as <a href="https://nsidc.org/data/modscgdrf_nrt/versions/1"> MODSCGDRF_NRT</a>. Data inputs for MODSCAG and MODDRFS used by the STC algorithm are derived from NASA historical MODIS/Terra surface reflectance data (<a href="https://lpdaac.usgs.gov/products/mod09gav006/">MOD09GA v006</a> before December 28, 2021 and <a href=https://lpdaac.usgs.gov/products/mod09gav061/>MOD09GA v061</a> onwards).The STC algorithm includes a suite of processes to improve the accuracy of MODSCAG/MODDRFS and adds additional information, notably snow albedo with and without the darkening from light absorbing particles. The STC algorithm accounts for off-nadir MODIS viewing geometry by weighting observations using the satellite view angle. STC uses the time series of data to better identify clouds whereas MODSCAG and MODDRFS use spectral tests which frequently include errors of omission and commission. STC uses forest height and the associated fractional vegetation simultaneously retrieved by MODSCAG for the same date and time to create an on-the-ground snow cover fraction. Finally, viewable snow cover fraction is used to remove biased retrievals of other variables. The resulting data is interpolated, resulting in a near-complete dataset. In addition, while the MODSCAG data sets do not include snow albedo, STC calculates clean snow albedo and snow albedo darkened by light absorbing impurities assuming both horizontal and sloped surfaces. This data set contains the following parameters: snow fraction (viewable and on the ground), snow albedo (clean and observed; on flat and on slope), snow darkening, snow radiative forcing, and snow grain size (from spectral mixture and the normalized difference grain size index). Data are available from 01 March 2000 to 30 September 2023 and are currently available for the western United States (MODIS tiles h08v04, h08v05, h09v04, h09v05, h10v04). MODIS tiles are provided in the Sinusoidal projection derived from input MOD09GA files. Additional tiles will be added over time. These data are provided in the netCDF-4 format with a Sinusoidal projection.
Historical Urban Population: 3700 BC - AD 2000
The Historical Urban Population, 3700 BC - AD 2000, originally developed by the Yale School of Forestry & Environmental Studies, is the first spatially explicit global data set containing location and size of urban populations over the last 6,000 years. The data set was created by digitizing, transcribing, and geocoding historical, archaeological, and census-based urban population data. Each data point consists of a city name, latitude, longitude, year, population, and a reliability ranking to assess the geographic uncertainty of each data point. Despite spatial and temporal gaps, no other geocoded data set at this resolution exists. It can therefore be used to investigate long-term historical urbanization trends and patterns, evaluate the current era of urbanization, and build a richer record of urban population through history.
International Polar Year Historical Data and Literature, Version 1
The International Polar Year Historical Data and Literature collection (formerly known as the Discovery and Access of Historic Literature from the IPYs (DAHLI) project) is an online data collection consisting primarily of photographs, publications, and observational data records from, and relating to, the first two International Polar Years (IPY) 1882-83 and 1932-33 and the International Geophysical Year (IGY)1957-58. Examples of data contained in observational records include, but are not limited to: air magnetic vertical intensity, air conductivity, atmospheric-electric observations, auroral log data, potential-gradient electrographic data, dust counts, and meteorological observations. Photographs within the collection include those from the Wilkes Station in Antarctica, the USGS survey of Fletcher's Ice Island, and the DTM Geophysical Laboratory Library. Publications within this collection primarily consist of government (national and international) bulletins and reports on activities during the International Polar and International Geophysical years. Other data include audio files of interviews recorded during NCAR's Oral Histories Project, and a video on Drifting Station Alpha during the IGY, published by NSIDC.
Historical MODIS/Terra L3 Global Daily 500m SIN Grid Snow Cover, Snow Albedo, and Snow Surface Properties, Version 1
This data set contains the following parameters: snow fraction (on the ground), viewable snow fraction, snow cover duration, snow grain size, dust concentration, snow albedo (on horizontal surface), snow albedo (on sloped surface), and radiative forcing. All variables are spatially and temporally complete after interpolation. Days without observation is also included so that users can determine how many days since a satellite observation occurred. The data set is derived from a version of the spectral mixture analysis (SMA) approach called the Snow Property Inversion from Remote Sensing (SPIReS, <a href="https://www.sciencedirect.com/science/article/pii/S0034425725001464?via%3Dihub#bb0040">Bair et al, 2021</a>). This dataset uses surface reflectance inputs from <a href="https://lpdaac.usgs.gov/products/mod09gav061/">MOD09GA v6.1</a> and includes additional outputs not included in the original version of SPIReS: snow albedo and snow radiative forcing. The SPIReS SMA model considers three spectral endmembers: snow, shade, and a snow-free background reflectance, which is identified for each MODIS pixel as the average MOD09GA reflectance measured typically between 1 August and 30 September for a given year in the northern hemisphere. dust concentration is solved for simultaneously with fractional snow cover and snow grain size during the spectral unmixing process. SPIReS snow albedo are derived using a lookup table that incorporates snow grain size, dust concentration, and surface illumination (<a href="https://www.sciencedirect.com/science/article/pii/S0034425725001464?via%3Dihub#bb0025">Bair et al., 2019</a>). After the fSCA, grain size, and dust concentration are determined, these properties are filled, smoothed, and adjusted for canopy gap size, shade, and permanent ice. SPIReS radiative forcing are derived using a lookup table that incorporates LAP concentration and clear sky incoming solar irradiance. Data are available from 01 March 2000 to 30 September 2024. These data are provided in the netCDF-4 format with a Sinusoidal projection and are currently available for the western United States (MODIS tiles h08v04, h08v05, h09v04, h09v05, h10v04). Additional tiles will be added over time. For data after 30 September 2024, please see the near real-time dataset (<a href="https://doi.org/10.7265/hs6b-zg21">Rittger et al., 2025</a>) created by Snow Today at NSIDC.Data can be accessed via ftp://dtn.rc.colorado.edu/shares/snow-today/spires/SPIRES_HIST_V01
