Multi-Network Composite 5mb Vertical Resolution Sounding Composite



This data set contains a composite of the of interpolated 5hPa resolution upper air sounding data from all sources for the Remote sensing of Electrification, Lightning, And Meso-scale/micro-scale Processes with Adaptive Ground Observations (RELAMPAGO) project in the EOL Sounding Composite (ESC) columnar ASCII format. The data set contains 2714 soundings including the Colorado State University (CSU) mobile radiosondes (105 soundings), the Center for Severe Weather Research (CSWR) mobile radiosondes (266 soundings), the University of Illinois (UIUC) mobile radiosondes (206 soundings), the DOE/ARM CACTI soundings from their two sites (1255 soundings), the INPE radiosondes from Sao Borja, Brazil (58 soundings), as well as the radiosondes from six locations around central Argentina that were operated by Servicio Meteorol√≥gico Nacional (SMN; 824 radiosondes).

Additional information

Data Quality final
  • 1.0 (2019-06-14)
  • 1.1 (2019-09-09):

     Additional networks have been added to this composite. 

  • 1.2 (2020-01-07):

    This version corrects an issue with the CSWR and UIUC radiosonde data quality flags. CSWR noted that they mislabeled their dew point data quality flag as a wind direction quality flag in their documentation and these flags were translated into the EOL composite files. This version has adjusted the flag translations to account for this. The only impacts are to the qrh, qu, and qv data quality flags, no data values have been changed.

  • 1.3 (2020-03-25):

    This version includes an update to the CSWR and UIUC radiosonde. The surface wind speed and direction have been updated and they also added additional some objective/subjective flags.

(Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
