Group: Summary

   This data set consists of solar and longwave radiation data from beneath two 
   pine canopies (one uniform, one discontinuous) at the Local Scale Observation 
   Site (LSOS) of the Cold Land Processes Field Experiment (CLPX) in northern 
   Colorado. The LSOS is a 100 x 100-m study site located within the Fraser 
   Intensive Study Area (ISA). The study area has flat topography with both a 
   dense pine stand and an open pine stand. Data were collected during February 
   and March 2002 and 2003. 

   This work addresses two of the overall CLPX questions: (1) How do the extent 
   and evolution of snow and frozen landscapes affect fluxes, storage, and 
   transformations of water, energy, and carbon? (2) At what scales does spatial 
   variability of key state variables in the cryosphere (including snow 
   characteristics, soil moisture, the extent of frozen soils, and the transition 
   between frozen and thawed conditions) control fluxes and transformations of 
   water, energy, and carbon, and can remote sensing resolve this variability at 
   these scales? 

   The NASA CLPX is a multi-sensor, multi-scale experiment that focuses on 
   extending a local-scale understanding of water fluxes, storage, and 
   transformations to regional and global scales. Within a framework of nested 
   study areas in the central Rocky Mountains of the western United States, 
   ranging from 1-ha to 160,000 km2, intensive ground, airborne, and spaceborne 
   observations are collected. Data collection focuses on two seasons: 
   mid-winter, when conditions are generally frozen and dry, and early spring, a 
   transitional period when both frozen and thawed, dry and wet conditions are 
   widespread.
