3-Hourly NCEP North American Regional Reanalysis (NARR) Composites


Plot composites (averages) of the hourly mean. NARR dataset. NARR data is available from Jan 1979 to Oct 31, 2018 for 0z,3z,6z,9z,12z,15z,18z,21z Note that accumulated precipitation is accumlated from the time to 3 hours later. The precipitation rate is the forecast for 3 hours later. In general for precipitation, you should use accumulated precipitation.

The NARR dataset is very high resolution. Please have patience while plots are being created.
