A new Arctic-Boreal Vulnerability Experiment (ABoVE) dataset, Climate Drivers of Pan-Arctic Tundra Vegetation Productivity, 1982-2015 is available at NASA’s Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC). Data collected over 33 years were compiled to observe seasonal trends of vegetation productivity and to detect dynamics between Arctic vegetation and climate drivers. Climate drivers include (1) maximum normalized difference vegetation index (NDVI) and time-integrated NDVI, (2) summer sea ice concentrations, (3) oceanic heat content, (4) land surface temperature, and (5) summer warmth index. NASA’s ABoVE field campaign in Alaska and Canada links field-based data with geospatial data products created from airborne and satellite missions.

Three new Deep Blue aerosol products derived from the joint NOAA/NASA Suomi National Polar-orbiting Partnership (Suomi-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) instrument data are now available through NASA’s Level 1 and Atmosphere Archive and Distribution System (LAADS) Distributed Active Archive Center (DAAC). The VIIRS Deep Blue aerosol product uses the Deep Blue (DB) algorithm over land and Satellite Ocean Aerosol Retrieval (SOAR) algorithm over water to determine atmospheric aerosol loading for daytime cloud-free snow-free scenes. Along with VIIRS, the DB algorithm also can be used with aerosol data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) instruments.

Data from the Saildrone wind and solar powered unmanned surface vehicle (USV) field campaign over the California and Baja coasts is now available at NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC). The Saildrone Baja campaign took place from April 11 through June 11, 2018. Along with establishing the utility of data from the Saildrone platform for assessment of satellite data accuracy and model assimilation, campaign objectives included studies of ocean upwelling and frontal region dynamics, air-sea interactions, and diurnal warming effects.
