The only field *at this resolution* that we typically force HYCOM with is the total precipitation (ttlpcp). The reason for doing this is because we don't have it at finer resolution until it started for 0.5a sometime in 2008. (We never got ttlpcp for nogaps0.5c.) We suggest you only use the ttlpcp files in the nogaps1.0a/3hourly directory. Grab the finer resolution 0.5a or 0.5c output for the other forcing fields. For precip, only the 'std' files are needed.

e.g.,

nogaps1.0a-std_2002_03hr_ttlpcp.D
nogaps1.0a-std_2003_03hr_ttlpcp.D
nogaps1.0a-std_2004_03hr_ttlpcp.D
nogaps1.0a-std_2005_03hr_ttlpcp.D
nogaps1.0a-std_2006_03hr_ttlpcp.D
nogaps1.0a-std_2007_03hr_ttlpcp.D
nogaps1.0a-std_2008_03hr_ttlpcp.D
nogaps1.0a-std_2009_03hr_ttlpcp.D

We stopped processing nogaps1.0a ttlpcp a while ago because we were getting it on the 0.5a grid, thus the 2009 file above is very small and may only contain a few time points.
