National Weather Service High Resolution Radiosonde Data (EOL Format) [NCAR-EOL]



The National Weather Service (NWS) routinely releases radiosondes at 00 and 12 UTC with occasional special releases at sites throughout the United States. This data set includes the quality controlled Tropical Cyclone Intensity (TCI) NWS soundings released at sites near the locations of TCI flown tropical cyclones. TCI flew two storms in the Atlantic (Erika and Joaquin) and two storms in the eastern Pacific basin (Marty and Patricia). For Erika, this data set includes soundings from 25-30 August 2015 from Key West, Miami, Tampa Bay, and San Juan. For Joaquin, the included soundings are from 25 September to 6 October 2015 from Albuquerque, Albany, Birmingham, Amarillo, Brownsville, Buffalo, Caribou, Chatham, Corpus Christi, Del Rio, Greensboro, Fort Worth, Gray, Sterling, Lake Charles, Wilmington, Lincoln, Jackson, Slidell, Little Rock, Midland, Nashville, Norman, Pittsburgh, Blacksburg, Shreveport, Key West, Miami, Jacksonville, Charleston, Tampa Bay, Tallahassee, Newport, Upton, and San Juan. For Patricia, the included soundings are from 19-24 October 2015 from Brownsville and Corpus Christi. Marty was not near any NWS sounding locations. A total of 1059 quality-controlled, high vertical resolution (1-second) soundings are contained in the final TCI data set.

Archive note

On 2/6/2019, new soundings were added to this dataset to cover the time period when the High Ice Water Content (HIWC) Radar Study project was operating out of Fort Lauderdale, Florida. The 666 new soundings are from 8/9/2015 through 8/25/2015.
