Following the conclusion of our second and final DCOTSS deployment, real-time product generation has ceased
(effective 11 July 2022).

Our gridded NEXRAD WSR-88D radar data (GridRad) is produced in near-real-time to support forecasting and flight planning activities for our NASA field project, DCOTSS. GridRad volumes are made every 10 minutes, include radar reflectivity at horizontal polarization and radial velocity spectrum width and are delivered with a latency of approximately 30-40 minutes (i.e., 30-40 minutes prior to the current time). Instantaneous maps of column-maximum radar reflectivity and 15-dBZ echo top altitudes, and animations of recent time periods for the full GridRad domain (235–294ºE longitude, 24–50ºN latitude) and seven sub-domains over the United States are provided via the link below. See Research page for more information on GridRad and DCOTSS.

In addition, real-time GOES-16/17 satellite imagery has been made available by our collaborators at NASA and is also included via link below (both national maps and eight sub-domains – those used for GridRad, plus one over the Sierra Madre Occidental and one over the Gulf of Mexico), with similar latency to that for GridRad. DCOTSS-specific products, including tropopause-overshooting convection analyses from GridRad and GOES and forecasts (using a trajectory model driven by NCEP GFS forecast winds) and some supporting NCEP GFS forecast tropopause characteristics are also available below.

This page was created in June 2019 and is under routine development (latest significant updates in April 2021). Requests for adding alternative GridRad products to this page may be sent to Dr. Cameron R. Homeyer and in time they may appear. Requests for additional NCEP GFS forecast products may also be made, but requests for additional GOES products are unlikely to be fulfilled.
