Using GFE as a DHM Grid Editor

ABRFC testing
• Prototype procedure developed for “GFE at the RFCs” OSIP project.
• Uses ABRFC-developed tools to read / write XMRG-formatted data into / from GFE.
• Uses existing GFE smart tools to modify the imported data

Details…• Proof-of-concept only. Procedure tested on
precipitation data but can work for any XMRG-formatted data (e.g. soil moisture). Needs modifications for more general use.
• NWSRFS-like “mods” are performed on the data with mathematical GFE smart tools.
• Examples:– Use the “Adjust” tool for “RRIMULT.”– Use “Assign Value” tool for “RRICHNG.”

Details…
• Testing with default GFE projection showed unacceptable data distortions were introduced when translating from / to HRAP while reading / writing XMRGs.
• ABRFC now runs GFE server on HRAP projection – suitable for current operational use.
