EOSDIS New Datasets: December 2017
NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) published the dataset “Version 2.3 ozone (O3) BUV-like profile data product”. This dataset provides ozone mixing ratios, reported at 15 pressure levels between 50 and 0.5 hectoPascals. Additionally, this data product contains measurements of total ozone, UV aerosol index, and reflectivities at 331 and 380 nm. The dataset time range is 2011-11-07 to present. The spatial coverage of the data is global (-82⁰ to +82⁰ latitude), and each day typically has 80 profiles. The footprint size is 250 km x 250 km. The data were derived from data acquired by the Ozone Mapping and Profiler Suite (OMPS) Nadir Profiler (NP) instrument on the joint NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) satellite.
GES DISC published the dataset “NASA Ozone Monitoring Instrument (OMI) aerosol product generated by the version 126.96.36.199 OMAERUV algorithm”. This dataset provides aerosol optical depth, aerosol absorption optical depth, single scattering albedos, and aerosol index data products. The data time range is 2004-10-01 to present, and are provided at 13 km x 24 km spatial resolution. The data were derived from measurements taken by the OMI instrument on the Aura satellite.
GES DISC released the Earth Science Data Record (ESDR) “Sulfur Dioxide”. This dataset provides atmospheric SO2 concentrations. The dataset covers the entire period of the S-NPP/OMPS mission, from launch in October 2011 to the present, with forward data processing ongoing. The data are provided at 50 x 50 km spatial resolution. The data were derived from backscatter Ultraviolet (BUV) measurements from the OMPS Nadir Mapper (NM), flown on the Suomi-NPP satellite.
GES DISC published the dataset Microwave Limb Sounder (MLS) version 4.2 near-real-time (NRT) data. This upgrade increases the vertical height range of the NRT temperature product to provide additional coverage in the upper stratosphere/ lower mesosphere (up to 0.001 hectoPascals). For those currently using the version 3 NRT products, it is expected to continue to be produced in parallel with version 4 NRT for the next several months, nominally until 1 April 2018, at which time the v3 NRT processing will be discontinued. The data are derived from MLS retrievals. NRT data do not have digital object identifier (DOI) reference listings.
NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) published three datasets from the Global Precipitation Measurement Ground Validation (GPM-GV) program. Two datasets were collected during the Olympic Mountain Experiment (OLYMPEX) held on the Olympic Peninsula in the Pacific Northwest of the United States between November 2015 and January 2016. The third is from the Integrated Precipitation and Hydrology Experiment (IPHEx), which took place in North Carolina in the spring of 2014.
GPM-GV Two-Dimensional Video Disdrometer (2DVD) OLYMPEX
Collected from four sites, the data contains daily ASCII-tsv files with information on individual hydrometeors including the number of hydrometeors, raindrop size distribution, and particle concentration. The data range from October 31, 2015 through January 17, 2016; exact dates may vary per site.
GPM-GV Cloud Radar System (CRS) OLYMPEX
This dataset provides radar reflectivity and Doppler velocity data used to estimate cloud droplet distribution for the storms monitored during the field campaign. The CRS instrument is a 94GHz W-band Doppler radar with a 3mm wavelength. CRS can be deployed as both an airborne instrument onboard NASA’s high-altitude science aircraft, the Earth Resource 2 (ER-2), as well as a ground based radar system. Only the airborne mode was used during OLYMPEX. In addition to reflectivity and Doppler velocity, the data files include aircraft flight information. The CRS was flown on 10 different days between November 10, 2015 and December 10, 2015. Each data file contains one hour of flight measurements during flight in UTC time. Files for this dataset are in netCDF-3 format and readily accessible without the need of specialized software.
GPM-GV Southern Appalachian Rain Gauge IPHEx
Rain gauge data from 45 observation sites are available in ASCII-csv format from January 3, 2008 thru December 31, 2014.

NASA's Socioeconomic Data and Applications Center (SEDAC) released the dataset, Global Population Projection Grids Based on Shared Socioeconomic Pathways (SSPs), 2010-2100, on 8 December as part of the SEDAC Population Dynamics data collection. The dataset provides global gridded population projections at a resolution of 7.5 arc-minutes for urban, rural, and total population, consistent both quantitatively and qualitatively with the SSPs at ten-year intervals for 2010-2100. Spatial demographic projections are key inputs into studies of future land use, energy use, and emissions and the assessment of climate change vulnerability, impacts, and adaptation.
SEDAC released two related datasets developed by E. Brown de Coulston of NASA's Goddard Space Flight Center and colleagues on 8 December, together with an interactive data visualization and access tool. The Global Man-made Impervious Surface (GMIS) Dataset From Landsat consists of global estimates of fractional impervious cover at 30-meter resolution derived from the Global Land Survey (GLS) Landsat dataset for the target year 2010. GMIS includes 2 layers: global percent of impervious cover and per-pixel associated uncertainty for the global impervious cover. The Global Human Built-up And Settlement Extent (HBASE) Dataset from Landsat also has two layers: the HBASE mask and the pixel-wise probability of HBASE. The HBASE mask was created for post-processing of the GMIS dataset, but can also be utilized by users needing a binary map. All of the layers are co-registered to the same spatial extent at a common 30-meter spatial resolution. These datasets are expected to support urban land cover studies from local to global scales as well as those modeling climate/environmental impacts of man-made surfaces.
The data may be viewed and subsetted using a 4-panel map interface adapted from the SEDAC Map Viewer: http://sedac.ciesin.columbia.edu/mapping/gmis-hbase/explore-view/.
