The IDNR has revised the anemometer height from 10 meters to 7.9 meters at the Cedar Rapids meteorological data station (call sign KCID) to reflect the correct height for this station. The revised surface and upper air KCID meteorological data files are available on the IDNR's Dispersion Modeling page. New meteorological data sets for the time period 2010 through 2014 will be available in the near future for all areas in the State of Iowa but dispersion modeling analyses that utilize KCID meteorological data should use the revised 2005 through 2009 dataset in the interim.
