ICOADS C36 Full CSV File README This README file is representative of the ICOADS csv flux files for the COARE 3.6 algorithm. This includes additional input and output variables that are otherwise omitted from the final netCDF product due to redundancy, lack of user interest, etc. The file format for these csv files are as follows: {algorithm}_ICOADS_{month}_{year}_{NOC}_{version}.csv Please note that NOC values are present in both NOC replaced files and their non-NOC counterparts. The information is present in both, but is only utilized in the NOC flux files. For further information regarding COARE input/output, please refer to the original documentation: https://github.com/NOAA-PSL/COARE-algorithm/blob/master/Python/COARE3.6/coare36vn_zrf_et.py --- Variables present: uid (Base 36) - ICOADS unique record identfier id - ICOADS platform identification/call sign date - Date of record in MM/DD/YYYY format.
