EOSDIS Data News: August 17, 2018
NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) published the Cross-track Infrared Sounder (CrIS) Level 1B data Version 2 data products for both Normal Spectral Resolution (NSR, SNPPCrISL1BNSR) and Full Spectral Resolution (FSR, SNPPCrISL1B).The NSR dataset contains lower resolution data in the shortwave and midwave, compared to the longwave, with a data start date of April 19, 2012. The FSR dataset contains the same spectral resolution in all three bands with a start date of November 2, 2015. Processing of the Level 1B Version 2 included several changes, which are listed in the Level 1B Product User’s Guide.

NASA's Land Processes Distributed Active Archive Center (LP DAAC) has re-published the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Vegetation Continuous Fields (VCF) Yearly Global 0.05 Degree Version 1 data product (VCF5KYR). The data product has been reprocessed to correct errors discovered after the data were initially released. VCF5KYR provides global fractional vegetation cover (FVC) at yearly intervals from 1982 to 2016. FVC is a primary means for measuring global forest cover change. The VCF5KYR data product contains layers for percent of tree cover, non-tree vegetation, and bare ground.
NASA's Oak Ridge National Laboratories DAAC (ORNL DAAC) published the Earth Venture Suborbital-2 (EVS-2) Atmospheric Tomography Mission (ATom) dataset ATom: Simulated Data Stream for Modeling ATom-like Measurements. This dataset provides a simulated data stream representative of an ATom data collection flight and also modeled reactivities for ozone (O3) production and loss and methane (CH4) loss from six global atmospheric chemistry models. The simulated data include concentrations of selected atmospheric trace gases for 14,880 air parcels along a simulated north-south ATom flight path along 180-degrees longitude over the Pacific basin. Each of the six models produced ozone production and loss and methane loss reactivities initialized using the simulated data beginning with five different days in August (8-01, 8-06, 8-11, 8-16, 8-21). Modeled years for each individual model varied from 1997 to 2016.
ORNL DAAC revised the ORNL DAAC Moderate Resolution Imaging Spectroradiometer (MODIS) Subsets dataset MODIS and Visible Infrared Imaging Radiometer Suite (VIIRS) Land Product Subsets RESTful Web Service. The MODIS/VIIRS Web Service provides data access capabilities for several MODIS Collection 6 and VIIRS (Version 001) land products. The web service provides data access functions for users to execute on their local computing resources. The web service is built upon the ORNL DAAC's MODIS/VIIRS Global Subsetting and Visualization Tool that provides customized subsets and visualization of land products for any land location on earth. With the web service users can retrieve land product subsets through command line operations; download and integrate subsets directly into client-side workflows; download and visualize subsets with customized code; and download subsets and write custom code for data reformatting.
ORNL DAAC revised the ORNL DAAC MODIS Subsets dataset MODIS and VIIRS Land Products Fixed Sites Subsetting and Visualization Tool. The MODIS/VIIRS Fixed Sites Subsetting Tool provides customized subsets and visualizations of several MODIS Collection 6 and VIIRS (Version 001) land products for 2000+ selected field and flux tower sites around the world. Spatial subsets of the land products are available for predefined areas (approximately 8.5 by 8.5-km) centered on each site. Users select a site and data product through the graphical web interface and are directed to a page with options for data download and visualizations.
ORNL DAAC revised the ORNL DAAC MODIS Subsets dataset MODIS and VIIRS Land Products Global Subsetting and Visualization Tool. The MODIS/VIIRS Global Subsetting and Visualization Tool provides on-demand, customized subsets of several MODIS Collection 6 and VIIRS (Version 001) land products. Data are available to the user through an interactive web page. The user specifies data product of interest and the area of interest by entering geographic coordinates or selecting the location on a map. Data are provided in either the native sinusoidal or geographic (WGS84) projection. Subsets are processed and delivered to the user via email. To view and download the data order, a user is provided with a custom order visualization page with interactive time series plots, data quality information, land cover and phenology data, order and product citations, and download access for the data in tabular and spatial data formats.
