* What is Surface Temperature
The surface temperature is the "skin" temperature. Over water, it is the
SST. Over land, it would be the "radiative" temperature of the surface. The
skin temperature is generated from the land surface model. Note, the skin
temperature is not the top layer soil temperature. During the day, the surface
temperature is typically higher than the soil and 2 meter air temperature.

Detailed Description:
- The NARR project is an extension of the NCEP Global Reanalysis which is run over the North American Region. The NARR model uses the very high resolution NCEP Eta Model (32km/45 layer) together with the Regional Data Assimilation System (RDAS) which, significantly, assimilates precipitation along with other variables. The improvements in the model/assimilation have resulted in a dataset with substantial improvements in the accuracy of temperature, winds and precipitation compared to the NCEP-DOE Global Reanalysis 2. We currently have output from Jun 2006 which includes 8 times daily data at 29 levels and most of the variables. For a complete list of model output variables, see NCEP's variable list.
- Additional information can be found at NCEP's NARR page.
- A discussion of the sign convention for radiative fluxis is available.
Caveats:
- Useful information can be found at NCEP's NARR FAQ page and from Albany's Department of Atmospheric Science NARR Usage Notes .
- The acpcp values for 0Z 1 October 1994 and 3Z 11 June 2005 seem to be in error.
Related File Naming & Structure Information:
File Names:
- 8-times daily and daily File names are composed of variable abbreviations and year: (variable).(year).nc(In directory: /Datasets/NARR/monolevel/ or /Datasets/NARR/Dailies/monolevel)
- Monthly means/ltms are (variable).mon.mean.nc in /Datasets/NARR/Monthlies/monolevel
Dataset Format and Size:
- All data are stored in PSL standard NetCDF4 files
- The data are divided by variable and year into separate files
- There are 2100 files currently
- Size of file is about 1.4G per variable per year/month for 8xdaily data
- Size of file is about 68M per variable per /month for monthly data
- Current total of 29.4 Tbytes for 8xDaily.
- 8x daily data are available from ftp.cdc.noaa.gov in /Datasets/NARR/.
- The 8x data files are quite large, so you may only be able to download them if you have a fast network connection.
Missing Data:
- Missing data is flagged with a value of 9.96921e+36f.
Citation:
- Please note: If you acquire NARR data products from PSL, we ask that you acknowledge us in your use of the data. This may be done by including text such as NARR data provided by the NOAA/OAR/ESRL PSL, Boulder, Colorado, USA, from their Web site at / in any documents or publications using these data. We would also appreciate receiving a copy of the relevant publications. This will help PSL to justify keeping the NARR data set freely available online in the future. Thank you!
