EOSDIS Data News: November 3, 2017
NASA's Goddard Earth Science Data and Information Service Center (GES DISC) published the Nimbus 7 Temperature-Humidity Infrared Radiometer (THIR) Level 1 Cloud Data for SBUV/TOMS (BCLT) product was released to the public. The THIR data are averaged each orbit onto each of the Nimbus 7 TOMS and SBUV IFOVs. These data are available from October 31, 1978 through October 27, 1984. In the THIR, the 6.7 μm channel gave information on the moisture content of the upper troposphere and stratosphere and the location of jet streams and frontal systems. The 11.5 µm channel provided both day and night cloud top or surface temperatures.
GES DISC began rolling out the Orbiting Carbon Observatory – 2 (OCO-2) Version 8 dataset. In the initial phase, only the highest quality, "retrospectively" processed data are being released. V8 has been processed with an updated version of the OCO-2 Level 1 (L1) and Level 2 algorithms. The latest versions of the algorithms include updated radiometric calibration for the L1B product; updated spectroscopic parameters; addition of stratospheric aerosols; and a more realistic treatment of surface reflectance in the L2 algorithm.
GES DISC released eight new Carbon Monitoring System (CMS) Carbon Flux (CMS-Flux) datasets. These datasets contain global estimates of various components of the carbon cycle, constrained by satellite observations, produced by CMS-Flux carbon cycle data assimilation system. The total CO2 flux, which is the net sum of all carbon fluxes, is currently available for 2010 through 2012; however, the dataset will eventually be extended through 2016.

NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published the Global Precipitation Measurement Ground Validation (GPM-GV) Advanced Vertical Atmospheric Profiling System (AVAPS) Olympic Mountains Experiment (OLYMPEX) dataset
This dataset contains dropsonde vertical profiles of atmospheric pressure, air temperature, dew point temperature, relative humidity, wind direction and magnitude, and sensor location obtained during the OLYMPEX. The AVAPS dropsondes were released during specific NASA DC-8 aircraft flights between November 12, 2015 and December 19, 2015. A total of 53 standard research dropsondes were dropped over the Pacific Ocean off the coast of Washington state that collected atmospheric profile observations. The AVAPS dataset is available in American Standard Code for Information Interchange (ASCII)-eol text format.
GHRC DAAC also published the GPM-GV Cloud Physics Lidar (CPL) OLYMPEX dataset
The dataset consists of extinction profiles, layer optical depth, layer lidar ratio, and aircraft parameter measurements measured by the CPL flown on the NASA ER-2 aircraft during the GPM OLYMPEX campaign. The CPL instrument is a multi-wavelength backscatter lidar that provides multi-wavelength measurements of cirrus and aerosols with high temporal and spatial resolution. Data files are available from November 9, 2015 through December 15, 2015 in HDF-5 format with measurement layer information in ASCII text files. Browse images in GIF format contain optical depth and flight path images.
NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the Carbon Monitoring System (CMS) dataset CMS: Lidar Data for Forested Sites on Borneo Island, Kalimantan, Indonesia, 2014. This dataset provides airborne lidar data collected over 90 sites totaling approximately 100,000 hectares of forested land in Kalimantan, Indonesia on the island of Borneo in late 2014. The data were collected as part of an effort to establish a national forest monitoring system for Indonesia that uses a combination of remote sensing and ground-based forest carbon inventory approaches.
ORNL DAAC published the CMS dataset CMS: Lidar-derived Canopy Height, Elevation for Sites in Kalimantan, Indonesia, 2014. This dataset provides canopy height and elevation data products derived from airborne lidar data collected over 90 sites on the island of Borneo in late 2014. The sites cover approximately 100,000 hectares of forested land in Kalimantan, Indonesia. The data were produced as part of an effort to improve a national forest monitoring system for Indonesia that uses a combination of remote sensing and ground-based forest carbon inventory approaches.
NASA's Socioeconomic Data and Applications Center (SEDAC) released the Global Population Projection Grids Based on Shared Socioeconomic Pathways (SSPs), v1 (2010-2100) on 23 October for beta testing as part of the SEDAC Population Dynamics data collection. These data consist of global spatial population projections at a resolution of one-eighth degree (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 for the analysis of land use, energy use, and emissions, as well as for the assessment of climate change vulnerability, impacts and adaptation. The SSPs were developed to support future climate and global change research and the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).
The India Annual Winter Cropped Area, v1 (2001-2016) dataset was released 27 October for beta testing as part of the SEDAC India data collection. These data consist of consist of annual winter cropped areas for most of India (except the Northeastern states) from 2000-2001 to 2015-2016. This dataset utilizes the NASA Moderate Resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI; spatial resolution: 250m) for the winter growing season (October-March). The methodology uses an automated algorithm identifying the EVI peak in each pixel for each year and linearly scales the EVI value between 0% and 100% cropped area within that particular pixel. Data were validated using high-resolution QuickBird, RapidEye, SkySat, and WorldView-2 images spanning 2008 to 2016 across 11 different agricultural regions of India.
