Mixing Height Data

The Mixing Height data offered here present twice daily (derived) values and are obtained from the National Climatic Data Center (NCDC), Asheville, North Carolina. All data/station files for a state are in TXT format and have been compressed into a single ZIP file for that state.   Before downloading mixing height data files please read an important message about these files.
Special note: All missing data values have been filled except where the guidelines for filling missing data could not be followed due to an excessive number of repetitive missing values. Please read the "Missing Meteorological Data Report" to identify those station/years that are not complete.Station List: Click HERE for a list of Mixing Height Stations available on SCRAM.
