Automated Surface Observing System (ASOS) 'Specials' Dataset



This dataset contains Automated Surface Observing System (ASOS) Surface "Special" observation surface data. This dataset is one of several surface datasets provided for the Cooperative Atmospheric Surface Exchange Study October 1999 (CASES 1999) project. The ASOS "Nominal" hourly surface data for the CASES 1999 domain and time period are included in the CASES 1999 ASOS hourly surface dataset. This ASOS "specials" dataset contains special or rare-event data from three stations within the CASES 1999 time period (25 September 1999 through 5 November 1999) and in the CASES 1999 domain (approximately 95.7438W to 97.7438W longitude and 36.6501N to 38.6501N latitude). No additional QC was performed by the University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS).
