gov.noaa.ncdc:C00048 National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce Unknown tabular digital data http://www.ncdc.noaa.gov Mixing Height is a historical digital data set archived at the National Climatic Data Center (NCDC). Major parameters which make up this file are date, morning type indicator, morning mixing depth, morning average wind speed through mixing depth, morning average surface wind speed, afternoon type, afternoon mixing depth, afternoon average wind speed thru mixing depth, and afternoon average surface wind speed. Mixing height tabulations produced and available at the NCDC are listed in the Index alphabetically by state and then rawinsonde data available is given first. Following the upper air dates are dates for which mixing height tabulations have been produced using the listed surface station data. The number of surface observations used in the tabulation is listed as 24 (hourly), 8 (3-hourly), 0 (or blank) (unknown). Tabulations were produced for a total of 62 stations from 1960 through 1964. These calculations were produced for the Environmental Protection Agency.
