OTREC_3DVar_Raymond_Fuchs-Stone

<p>This gzipped tar file supplies the complete data and analysis trail for the production of the OTREC project 3DVar analyses. &nbsp;The avaps branch includes directories for each flight, with names indicating the flight date in format yyyymmdd. &nbsp;Under each of these directories are the original dropsonde soundings from NCAR EOL in NetCDF format, as well as the regularized z-grid versions used for the 3DVar analysis, in Candis (doi:10.5281/zenodo.5150519) format. &nbsp;The actual 3DVar analyses (Z*) are in the subdirectories box*, depending on which OTREC box was flown. &nbsp;Bad soundings are moved to their own subdirectory so that they are not used in the 3DVar analysis.&nbsp; The analyses&nbsp;are named "merge-1.cdf". &nbsp;In addition, the shell script avapsbox.sh is included, by which the 3DVar analysis is performed for each case. &nbsp;This calls other scripts in the "script" directory. &nbsp;These scripts and the Candis executables must be in the user's path. &nbsp;Finally, in each directory is a "mask" file which defines the areal coverage of the dropsondes in each case. &nbsp;The other main subdirectory is called "avhrrsst", containing the sea surface temperature files from AVHRR satellite data. &nbsp;These data are referred to by the 3DVar calculation as well. &nbsp;Original AVHRR files from NOAA&nbsp;are included, as well as a shell script "otrec.sh" that puts needed SST data into the file "otrec_sst.cdf".</p><p>This version contains 3DVAR files translated from Candis to NetCDF format for the convenience of users. &nbsp;They are located in the same directories as the Candis files (otrec/avaps/2019/box/*) and have the file names of the form 2019mmdd-box*.nc.</p>
