gx1v3.313 11-15 5-year average (2000-2004). Equivalent to gx1v3.310, but lower viscosities.
gx1v3.314 5 1-year average (2004). Equivalent to gx1v3.310, but NCEP winds used in box 270E->300E, 40S->0S
gx1v3.315bv 11-15 5-year average (2000-2004). gx1v3.315bv is a 5-year QSCAT run with datm7.
gx1v3.315bv 12 gx1v3.310c 12 1-year average (2001). Equivalent to gx1v3.310c, but with new datm7 and time-varying precip and radiation and sea ice frac (all 2000->2004). gx1v3.315bv is the new QSCAT ocean-alone benchmark.

gx1v3.316 11-15 5-year average (2000-2004). gx1v3.316 is a 5-year NCEP run. It is equivalent to gx1v3.315bv except uses NCEP winds (ERROR: zero'd out ocean surface currents in this run!).
gx1v3.316 11-15 gx1v3.315bv 11-15 5-year average (2000-2004). gx1v3.316 is a 5-year NCEP run. It is equivalent to gx1v3.315bv except uses NCEP winds.
gx1v3.316a 8 gx1v3.316 8 gx1v3.316a is identical to gx1v3.316, except uses non-zero ocean surface velocities in flux computation.
gx1v3.318 11-15 5-year average (2000-2004). gx1v3.318 is a 5-year NCEP run identical to gx1v3.316 except: 1. it uses 2000-2004 wind magnitude correction, 2. a wind direction correction, and 3. new 2-D specific humidity correction.
gx1v3.318 11-15 gx1v3.316 11-15 5-year average (2000-2004). gx1v3.318 is a 5-year NCEP run identical to gx1v3.316 except: 1. it uses 2000-2004 wind magnitude correction, 2. a wind direction correction, and 3. new 2-D specific humidity correction.
gx1v4.319 11-15 gx1v3.318 11-15 5-year average. gx1v4.319 is identical to gx1v3.318, but uses new gx1v4 grid and associated files.
