OVERVIEW

Description/Abstract

Yearly topographically modified effective energy and mass transfer (EEMT-topo) (MJ m−2 yr−1) was calculated for the Valles Caldera, upper part of the Jemez River basin by summing the 12 monthly values. Effective energy and mass flux varies seasonally, especially in the desert southwestern United States where contemporary climate includes a bimodal precipitation distribution that concentrates in winter (rain or snow depending on elevation) and summer monsoon periods. This seasonality of EEMT-topo can be estimated by calculating monthly values using topographic variations of solar radiation, temperature, precipitation, evapotranspiration and surface wetting as described by Rasmussen et al. (2015). The following datasets were used to compute EEMT-topo: the precipitation climatology (1981-2010) data from the PRISM Climate Group at Oregon State Universityat an 800-m spatial resolution; the Jemez River Basin 2010 LiDARbased DEM dataset was up-scaled to 10 m DEM; the local meteorological data (Temperature, RH, Wind Speed and Pressure) downloaded for the Valles Caldera National Preserve Climate Stationsfrom 2003 to 2012; 2011 National Agriculture Imagery Program (NAIP) multispectral (4-band) images for the Valles Caldera downloaded from the USGS Seamless Data Distribution; and MODIS Albedo 16-Day L3 Global 500m data (MCD43A3) obtained from theLand Processes Distributed Active Archive Center (LP DAAC).

COMMENTS

Comments

The dataset could be used to identify sampling and instrumentation locations based on the surface energy input. Computation of EEMT-topo was designed to explicitly incorporate topographic variations in solar radiation, temperature, wind speed, vapor pressure deficit and water accumulation. http://www.czo.arizona.edu/czo_data/PublicData/Spatial/Jemez/EEMT_topo_description.pdf Detailed computation and data resources description.
