EOSDIS Data News: August 24, 2018


NASA's Atmospheric Science Data Center (ASDC), in collaboration with the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) mission team and the HYGEOS/AERIS/ICARE Data and Services Center, has announced the release of a new Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) Level 3 Stratospheric Aerosol Profile Product (V1.00). The CALIOP Level 3 Stratospheric Aerosol Profile monthly product reports global distributions of 532 nm total attenuated backscatter coefficients, attenuated scattering ratios, aerosol extinction coefficients, and stratospheric aerosol optical depths on a uniform three-dimensional spatial grid (5° latitude × 20° longitude × 900 m vertically). All level 3 parameters are derived from the nighttime CALIPSO version 4 level 1 and level 2 5-km merged layer products and the version 1.x level 2 polar stratospheric cloud data products. The monthly product is available beginning with data from June 13, 2006 through December 31, 2016.

NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC), in coordination with the European Space Agency and the Copernicus Sentinel Project, announced the availability of several datasets. They are the Sentinel-5 Precursor (S5P) TROPOspheric Monitoring Instrument (TROPOMI) Level-1B (L1B) and select Level-2 (L2) data products including UV Aerosol Index (UVAI), Cloud Product, Nitrogen Dioxide (NO2), and Carbon Monoxide (CO). Additional information on Sentinel-5P data are available from the Copernicus Project at https://sentinel.esa.int/web/sentinel/technical-guides/sentinel-5p/products-algorithms.
NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) has published the Hurricane and Severe Storm Sentinel (HS3) Statistical Hurricane Intensity Prediction Scheme (SHIPS) Intensity dataset. This dataset was a result of the HS3 field campaign. It consists of data from March 18, 2014 through September 30, 2014. Goals for the HS3 field campaign included assessing the relative roles of large-scale environment and storm-scale internal processes, addressing the controversial role of the Saharan Air Layer (SAL) in tropical storm formation and intensification, and the role of deep convection in the inner-core region of storms. The SHIPS model provides tropical storm intensity forecasts for tropical storms and hurricanes in the Atlantic Ocean and the eastern and central North Pacific Ocean. SHIPS uses Geosynchronous Earth Orbit Satellite (GOES) infrared imagery as input to the processing scheme. These SHIPS data are available in American Standard Code for Information Interchange (ASCII) format.
GHRC DAAC added Network Common Data Form (netCDF)-4 format data to the Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) on TRMM Science Data and on TRMM LIS Backgrounds data. TRMM LIS detected the distribution and variability of total lightning occurring in the Earth’s tropical and subtropical regions. The LIS Science Data consists of lightning and lightning density measurements for severe storm detection and analysis, as well as for lightning-atmosphere interaction studies. The LIS instrument made measurements during both day and night with high detection efficiency. These data are now available in both Hierarchical Data Format (HDF)-4 and netCDF-4 formats, with corresponding browse images in GIF format. The TRMM satellite stopped collecting data on April 8, 2015 and crashed in the Indian Ocean on June 15, 2015. Note that this dataset does not currently contain uniform algorithm processing over the length of operation. There are plans to reprocess the entire dataset in the future with an updated algorithm:


NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) has published an update to the dataset IceBridge ATM L4 Surface Elevation Rate of Change to include measurement comparisons of 2017 data to earlier years over Greenland. This dataset contains surface elevation rate of change measurements derived from IceBridge and Pre-IceBridge Airborne Topographic Mapper (ATM) wide scan elevation measurements data (ILATM1B) for missions flown under NASA’s Operation IceBridge and Arctic Ice Mapping projects.


NASA's Physical Oceanography DAAC (PO.DAAC) ingested the latest Making Earth System data records for Use in Research Environments (MEaSUREs) updates for the Integrated Multi-Mission Ocean Altimeter Data for Climate Research Version 4.2 dataset (Cycles 942 - 946) from B. Beckley. This update covers the period from April 10, 2018 to May 30, 2018.


NASA's Socioeconomic Data and Application Center (SEDAC) completed a production release of the Natural Resource Protection and Child Health Indicators (NRPI), 2017 Release dataset. The NRPI covers 234 countries and is calculated based on the weighted average percentage of biomes under protected status. The CHI is a composite index for 199 countries derived from the average of three proximity-to-target scores for access to at least basic water and sanitation, along with child mortality. The NRPI and CHI are part of a set of indicators used by the Millennium Challenge Corporation in its decisions about development assistance.

The Suomi National Polar-orbiting Partnership (Suomi NPP) Sounder Science Team and GES DISC released the Advanced Technology Microwave Sounder (ATMS) Level 1B data, Version 2. The three window channels of the ATMS at 23.8, 31.4, and 89 GHz provide information to compute total precipitable water, precipitation, information about cloud liquid water, sea-ice concentration, and snow cover. The window channel at 183 GHz channel is used to retrieve atmospheric humidity profiles. Processing of the Level 1B Version 2 included several changes, including modifications to geolocation, which are listed in the Level 1B Data Products user’s guide.
