Dear HS3 PI's and Researchers, As many of you may know, a temperature dependent dry bias in the relative humidity measurements was discovered in all dropsondes (RD94) and mini- dropsondes (NRD94) collected from 2010 to present. All four of the HS3 datasets, from 2011-2014, have had a correction applied to the RH measurements and dewpoint temperatures have been recomputed as well. The corrected data in native (EOL) format are available in these yearly directories. A CF-compliant netCDF version of these data will also be available soon. See the file Tech_Note_Dropsonde_Dry_Bias_20160527_v1.3.pdf in the "doc" directory for a detailed explanation of the temperature dependent dry bias.
