Forcings
- Temporal heterogeneities
corrected as described in Hamlet and Lettenmaier (2004, in review)
- Temperature and
precipitation records from the NCDC's Cooperative Observer station
meteorological daily data (TD3206: 1915 to 1949; and TD3200: 1950 to
2003)
- 2489 stations for
precipitation and 1904 for temperature gridded to 1/8 degree spatial
resolution then aggregated to ½ degree spatial resolution over
the North American Land Data Assimilation System (N-LDAS) domain
- Topographical
precipitation correction based on the PRISM precipitation maps (Daly et
al, 1994).
