***"fully adjusted temperature series"*** - "9641C_YYYYMM_F52.avg.gz" if you want the average of fully-adjusted monthly mean maximum and minimum temperatures (with estimates for missing values). ***"raw (unadjusted) temperature series"*** - "9641C_YYYYMM_raw.avg.gz" if you want the average of monthly mean maximum and minimum temperatures that are not bias adjusted. ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2/monthly/readme.txt
