The Cloud-Aerosol Lidar and Infrared Pathfinder (CALIPSO) mission team, in collaboration with NASA's Atmospheric Science Data Center (ASDC) and HYGEOS/AERIS/ICARE Data and Services Center, announces the release of an update to the standard Level 2 lidar data products.
Version 4.20 Lidar Level 2 Products
In-depth overviews for the products can be found in the following CALIPSO link to the data quality summaries:
NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) published a re-release of legacy TIROS (Television and Infrared Observation Satellite) Operational Vertical Sounder (TOVS) Pathfinder Path A Level-3 monthly Version 2 data products for TIROS N, NOAA-6 through NOAA-12, and NOAA-14. The products were reformatted at GES DISC into network Common Data Format (NetCDF) format. TOVS was one of the first long-term sources of high resolution global information pertaining to the temperature and moisture structure of the atmosphere. The data can potentially be used to identify and monitor trends in temperature, moisture, clouds, radiation, and precipitation.
GES DISC published the Level 2 Making Earth System Data Records for Use in Research (MEaSUREs) aerosol products OMIAuraAER (from OMI), TOMSEPAER (from Earth Probe-TOMS) and TOMSN7AER (from Nimbus 7 TOMS), which include UV Aerosol Index (UVAI), aerosol optical depth (AOD) and aerosol single scattering albedo (SSA), as well as calculated aerosol absorption optical depth (AAOD).
GES DISC released the Orbiting Carbon Observatory-2 (OCO-2) Lite product version 9, containing the most recent improvements in accuracy of the column-averaged CO2 dry-air mole fraction (xCO2). The first improvement is for a sub-footprint pointing offset that introduced 1-3 ppm biases in the V8 XCO2 retrievals in areas of with rapidly changing topography. The second improvement addressed an error affecting the a priori meteorological fields used in V8 retrievals. Finally, small adjustments in the data filtering algorithms were implemented to accept a larger fraction of the converged soundings collected over dark forested regions in the Tropics and Boreal regions. This version covers the period 2014-09-06 to 2018-09-01.
GES DISC is finalizing the acquisition and public release of Version 06 of the Global Precipitation Measurement (GPM) Precipitation Radar products. There are twenty data types, containing physical variables such as precipitation and latent heat release profiles.
NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) released the Hurricane and Severe Storm Sentinel (HS3) Cooperative Institute for Meteorological Satellite Studies (CIMSS) Tropical Overshooting Tops. GOES-15 Imager, METEOSAT-10 SEVIRI. August 14, 2014 to October 3, 2014
GHRC DAAC published the Hurricane and Severe Storm Sentinel (HS3) Cooperative Institute for Meteorological Satellite Studies (CIMSS) Tropical Overshooting Tops dataset. This dataset contains browse only data showing tropical overshooting tops derived from Meteorology Satellite (METEOSAT) and Geostationary Operational Envrionmental Satellite (GOES) satellites for the HS3 field campaign. 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 browse only data files are available for dates between August 14, 2014 and October 3, 2014 at 15 minutes intervals in KML format.
NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) released the Northern Hemisphere Equal-Area Scalable Earth (EASE)-Grid 2.0 Weekly Snow Cover and Sea Ice Extent for 23 October 1978 to 31 December 2017, and theAdvanced Microwave Scanning Radiometer for EOS (AMSR-E)/AMSR2 Unified L3 Daily 25 km Brightness Temperatures and Sea Ice Concentration Polar Grids for 7/2/2012 to present.
NSIDC DAAC released the AMSR-E/AMSR2 Unified L3 Daily 25 km Brightness Temperatures & Sea Ice Concentration Polar Grids. 7/2/2012 to present.
NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the North American Carbon Program (NACP) dataset CO2 Observations, Modeled Emissions, and NAM-HYSPLIT Footprints, Boston MA, 2013-2014. This dataset reports continuous atmospheric measurements of CO2 from two receptor sites and three boundary sites in and around Boston, Massachusetts, USA, that were combined with high-resolution CO2 emissions estimates and the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model to estimate regional CO2 emissions from September 2013 to December 2014. The HYSPLIT model followed an ensemble of 1,000 particles released at the urban CO2 measurement sites backward in time based on wind fields and turbulence from the North American Mesoscale Forecast System (NAM) at 12-km resolution to the boundary CO2 measurement sites to derive footprint values and CO2 enhancements expected from the prior emissions based on the Anthropogenic Carbon Emissions System (ACES) inventory and the urban-Vegetation Photosynthesis Respiration Model (urbanVPRM). This dataset contains three sets of data products:
- observed hourly mean CO2 observations for two urban receptor sites in Boston, MA (Boston University (BU) and Copley Square (COP))
- observed hourly mean CO2 and calculated vertical profiles (50 - 5000 m) for three boundary sites around Boston including Harvard Forest at Petersham, MA (HF), Canaan, NH (CA), and Martha's Vineyard, MA (MVY), and modeled mean boundary CO2 concentrations for particles released from BU and COP
- particle trajectory files including footprint values and CO2 enhancements above boundary CO2 concentrations from the HYSPLIT model.
NASA's Physical Oceanography DAAC (PO.DAAC) has released seven Aquarius datasets spanning 2011-Aug-26 to 2015-Jun-7: Aquarius CAP Level 3 Sea Surface Salinity Standard Mapped Image Monthly Data V5.0, Sea Surface Salinity, Wind Speed & Direction Data, Sea Surface Salinity Rain Corrected Standard Mapped Image 7-Day Data, Sea Surface Salinity Rain Corrected Standard Mapped Image Monthly Data V5.0, Level 3Wind Speed Standard Mapped Image 7-Day Data V5.0, Level 3 Sea Surface Salinity Standard Mapped Image 7-Day Data V5.0, and Level 3 Wind Speed Standard Mapped Image Monthly Data V5.0.

The sixth new dataset for RSS SMAP Level 2 Sea Surface Salinity V3.0 40km Validated Dataset was received, tested and operational ingestion is underway in preparation for public release.
On 12 October, NASA's Socioeconomic Data and Applications Center (SEDAC) released map services and maps for the Last of the Wild version 3 dataset (see: http://sedac.ciesin.columbia.edu/data/collection/wildareas-v3). The dataset includes a number of satellite-derived data layers, including University of Maryland Land Cover Classification, GlobCover, nighttime lights from the Defense Meteorological Satellite Program (DMSP)-Operational Linescan System (OLS), and SEDAC’s Global Agricultural Lands Pasture Lands, v1 dataset.
On 19 October, SEDAC released beta versions of the revised POPGRID website and the POPGRID map viewer, provide information and tools to compare a number of global population grid and settlement layers (see: http://beta.www.popgrid.org and http://beta.sedac.ciesin.columbia.edu/mapping/popgrid/). POPGRID is a data collaborative involving SEDAC and other major developers of population grids and settlement data, including many products that are modeled based on remote sensing inputs.
