Unidata's THREDDS Data Server (TDS) is a web server that provides metadata and data access for scientific datasets, using a variety of remote data access protocols.
A bug has been fixed in the THREDDS Data Server (TDS) NetCDF Subsetting Service (NCSS) that may, in rare cases, have returned incorrect results.
Surface thaw map for Alaska and Northwest Canada on April 25, 2003, derived from the Advanced Microwave Scanning Radiometer (AMSR-E).
A new dataset from NASA's CARVE mission provides the daily thaw state of the Alaskan land surface from 2003 - 2015.
Monthly mean CH4 flux estimates for Alaska. Values are centered on the mean measurement date for a given month and the shaded regions are the standard error of the mean (figure from Hartery et al. 2018).
A new dataset from NASA's Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) provides gridded methane flux estimates from 2012-2014.
Map of thawed land surfaces in Alaska as measured by the AMSR-E satellite radiometer on April 25, 2003.
New data from NASA's CARVE provides daily maps of the thaw state of Alaska's land surface from 2003 to 2014.
Photo taken on the 8 October 2015 CARVE flight above the Innoko National Wildlife Refuge in Alaska.
Photos and videos taken during CARVE flights, as well as daily flight reports, are now available online.
Infrared radiance of the land surface measured by the FLIR instrument onboard the CARVE flight on April 3, 2013.
A new data set provides measurements from the Forward Looking Infrared (FLIR) camera aboard the CARVE aircraft.
Surface contours for the average WRF-STILT influence functions show CO2 and CH4 measurements from the CARVE tower have a high sensitivity to the boreal forests and lowlands of interior Alaska (from Karion et al., 2016).
Two CARVE data sets provide modeled surface influence for particle receptors located at positions along CARVE flight paths and selected tower locations.
Total column CH4 retrievals from a CARVE flight on May 23, 2012, flying north from Fairbanks over the North Slope to Barrow.
Wind direction recorded outside the C-23 Sherpa aircraft during a CARVE flight on May 6, 2015.
A new dataset provides wind speed and direction data from CARVE flights in 2015.
Altitude and flight path recorded during a CARVE flight from Fairbanks to the North Slope of Alaska on November 7, 2014.
Flight path, height, pitch, roll, and heading information are available for the C-23 Sherpa aircraft during CARVE campaigns.
