NSIDC DAAC

NASA's National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has published the dataset Snow Experiment 2017 (SnowEx17) Ground Penetrating Radar Raw. This dataset contains the raw and unprocessed results of a ground penetrating radar survey conducted as part of the 2017 SnowEx campaign. Data were collected between 08 February 2017 and 25 February 2017 at Grand Mesa, Colorado.

NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the Atmospheric Tomography Mission (ATom) dataset, ATom: Aircraft Flight Track and Navigational Data. This dataset provides flight track and aircraft navigation data from ATom. Flight track information is available for the four ATom campaigns. Each ATom campaign consists of multiple individual flights and flight navigational information is recorded in 10-second intervals. Data available for each flight includes research flight number, date, and start and stop time of each 10-second interval. In addition, latitude, longitude, altitude, pressure and temperature is included at each 10-second interval. The ATom campaign deploys an extensive gas and aerosol payload on NASA's DC-8 aircraft for systematic, global-scale sampling of the atmosphere, profiling continuously from 0.2 to 12 km altitude. ATom establishes a single, contiguous, global-scale dataset. One intended use of this flight track data is to facilitate to mapping model results from global models onto the precise ATom flight tracks for comparison.
