You can also select files by entering a string below (*=any-string ?=1 character).   

Grib Filter

Grib Filter: Many times you may only want a section of a huge data file. Rather than transferring the entire file, this section will allow you to select some or all (1) levels, (2) variables, and (3) dates of a GRIB file. The buttons represent common choices which may or may not be relevant to the files that you want transferred. For example choosing RH (relative humidity) would be pointless in file of sea-surface temperatures. In addition, not all possibilities are allowed. For example, suppose you only want the virtual temperature at the tropopause at 01Z. Too bad because you have to transfer the entire file.

For GRIB data only.

Select the levels desired:
 all     10-200 cm down    0-10 cm down    2 m above gnd    10 m above gnd    atmos col    nom. top    sfc  

Select the variables desired:

Obtaining the Data

Your request will generate a data set. We can either (1) send the data our anonymous FTP server from which you can download the data or (2) FTP the data to your (anonymous) FTP server.

With the first method, you have to download the data within a preset time limit before the data are automatically deleted. THE SECOND METHOD IS NOT RECOMMENDED unless you have considered all the security implications and are willing to (a) send your FTP password over the internet in clear text, (b) have your FTP password saved in our web logs in clear text and (c) run an FTP server and (4) possibly make some holes in your firewall.
Save results on nomads6.ncdc.noaa.gov for downloading  FTP the results to your anonymous ftp server  
WARNING: This method will be stoped from using soon.
