NetSTORM can read and re-format either of two data formats from the US Historical Climatology Network (USHCN)dataset. USHCN data consist of daily and monthly timeseries for select US climatological stations. 

 

Daily data is available as single files for each of 48 US states. Each file contains precipitation, maximum and minimum temperature, snow fall, and snow depth data for all stations in the state. Data files available from cdiac.esd.ornl.gov/epubs/ndp/ushcn/usa.html look like this:

Monthly data are available as nationwide files for each data element. Files are available for precipitation, mean, maximum, and minimum temperature. Data files available from cdiac.ornl.gov/ftp/ushcn_monthly look like this:

The user must select whether to read the areal-edited (raw) or FILNET (gaps filled) datasets, and must select a state using standard postal codes. The program produces two output files with monthly and annual values respectively. The monthly file uses standard NetSTORM format, while the annual file is formatted as yyyy value station:
