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     1000 mb    925 mb    850 mb    700 mb    600 mb    500 mb    400 mb    300 mb    250 mb    200 mb    150 mb    100 mb    70 mb    50 mb    30 mb    20 mb    10 mb    atmos col    MSL    sfc  

Select the variables desired:
all     ABSV    HGT    RH    TMP    UGRD    VGRD    VVEL  

Extract Subregion

File transfer times can be reduced by only transferring a subregion. You can use this section to extract a geographic subsection from a latitude-longitude GRIB file. Use negative numbers for south and west.

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.
