Read precipitation data - read National Climatic Data Center (NCDC) precipitation time series from several standard formats or standard time series data
Read NOAA Summary of Day data - NetSTORM reads these data into an ASCII format. The user can select whether to read the entire dataset or a selected parameter. The format can be TD-3200 format or TD-3210 formats as shown below:

Read NOAA temperature data - NOAA daily minimum and maximum temperature data can be read into a format that can be used by SWMM or in NetSTORM to perform snowfall and snowmelt calculations. Temperature data can be contained in an FSOD file (shown above) , in NCDC-format temperature files obtained from the HydroData CDs in the following format:

or in NHDS archive files. If NHDS files are used, you can specify the same filename for the minimum and maximum temperature data file. The resulting temperature data file looks like this:

10/30/2001 0:00 41 55 27

Read NOAA Surface Airways hourly data - NOAA hourly temperature data can be read into a format that can be used by SWMM. Other types of 1984-2005 data can also be read.
