GHRC DAAC
NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) published beta versions of the Lightning Imaging Sensor on the International Space Station - LIS (ISS), non-quality-controlled standard products on September 17. These data are made available to users until a manual quality control process is complete, at which time they will be replaced by the archive version of the products.
- Beta Non-Quality Controlled LIS (ISS) Science Data
- Beta Non-Quality Controlled LIS (ISS) Backgrounds
These data are collected by the LIS (ISS) used to detect the distribution and variability of total lightning occurring in the Earth’s tropical and subtropical regions. These data can be used for severe storm detection and analysis, as well as for lightning-atmosphere interaction studies. The LIS instrument makes measurements during both day and night with high detection efficiency. The data are available in both Hierarchical Data Format (HDF)-4 and netCDF-4 formats. Data is available from 3/1/2017 forward.
GHRC DAAC published the Global Precipitation Measurement Ground Validation (GPM-GV) NASA S-Band Dual Polarimetric (NPOL) Doppler Radar Olympic Mountains Experiment (OLYMPEX) dataset. The dataset consists data and images from the NPOL radar during the GPM OLYMPEX campaign. NPOL, developed by a research team from NASA's Wallops Flight Facility, is a fully transportable and self-contained S-band (10 cm), scanning dual-polarimetric Doppler research radar that was placed near the ocean on the Olympic Peninsula, Washington. Data files are available from November 5, 2015 thru January 15, 2016 in Universal Format (UF), with browse imagery files in PNG format containing corrected radar reflectivity, differential reflectivity, specific differential phase, differential phase, co-polar correlation, and Doppler velocity images
GHRC DAAC published the GPM-GV Self-Calibrating Multivariate Precipitation Retrieval (SCaMPR) Integrated Precipitation and Hydrology Experiment (IPHEx) dataset which consists of rainfall rate measurements derived from GOES IR data using the SCaMPR algorithm. The SCaMPR algorithm is calibrated using satellite microwave rainfall estimates from the Special Sensor Microwave/Imager (SSM/I) and Advanced Microwave Sounding Unit (AMSU). This dataset contains SCaMPR rain estimates for the time period and spatial extent of the IPHEx campaign from April 30, 2015 to June 17, 2015.
GHRC DAAC published the Global Precipitation Measurement Ground Validation (GPM-GV) Advanced Microwave Precipitation Radiometer (AMPR) Olympic Mountains Experiment (OLYMPEX) dataset. AMPR is an airborne passive microwave radiometer from which cloud, precipitation, water vapor, wind speed and wind direction can be obtained using advanced algorithms with the 10.7, 19.35, 37.1, and 85.5 GHz microwave frequency brightness temperatures. The AMPR brightness temperatures were collected during the GPM OLYMPEX field campaign. AMPR data at GHRC DAAC include netCDF format data files of brightness temperature and PNG browse files of Quality Control Flags and Brightness Temperatures.

SEDAC
NASA's Socioeconomic Data and Applications Center (SEDAC) datasets, Global Population Count Grid Time Series Estimates, v1 (1970-2000) and Global Population Density Grid Time Series Estimates, v1 (1970-2000), were released on 13 October as part of the SEDAC Population Dynamics data collection. These datasets represent a “back-cast” time series of population count and density on a 30-arc-second (~1 km) grid over a 30-year period, using as a baseline the year 2000 population grid from SEDAC's Global Rural-Urban Mapping Project, Version 1 (GRUMPv1) dataset. Subnational population growth rates were adapted from the History Database of the Global Environment (HYDE) database, and population grids were adjusted so that country population totals equal the UN World Population Prospects (2008 Revision) estimates for each country for the years 1970, 1980, 1990, and 2000. These grids were developed as an input to the dataset, Global Estimated Net Migration Grids By Decade, v1 (1970-2000).
