Notes:
G. Leavesley. "... One issue with the NLCD classification is that deciduous and coniferous are not detailed enough for adequate estimation of things like rooting depth and interception storage. This is the reason I suggest using the LandFire data base and specifically the Society of American Foresters and the Range Management Society classifications that are contained in that data set."

Notes:
G. Leavesley. "... the 1 km grid of STATSGO data used by the weasel was generated by Dave Wolock in the USGS and provides average water holding capacity in units of depth per depth which can then be multiplied by the average rooting depth from the veg type data base to get the estimate of available water holding capacity for the HRU. He compared using a depth weighted average value with using just the precomputed single value for water holding capacity and found little difference between the two methods, so went with the simpler approach. The texture analysis is also an average value for the upper part of the profile..."
Notes:
G. Leavesley. "In the original version of PRMS the aspect was composed of the 8 points of the compass. In the newer implementation of PRMS, the concept of radiation planes has been abandoned and the computed aspect in degrees is used for each HRU. This results in the development of a table of potential radiation values that is 366 x (NHRU + 1) in size. The plus 1 is the horizontal surface set of potential values computed for the basin centroid latitude."
