The folder fisherETmdl.tar.gz contains an IDL script (grandLE01) for computing daily global latent heat and latent heat components (canopy, wet canopy, and bare soil) according to Joshua B. Fisher, Kevin P. Tu, Dennis D. Baldocchi, Global estimates of the land–atmosphere water flux based on monthly AVHRR and ISLSCP-II data, validated at 16 FLUXNET sites, Remote Sensing of Environment, Volume 112, Issue 3, 18 March 2008, Pages 901-919. Potential evapotranspiration, which is used to parameterize the latent heat model, is also produced using PRIESTLEY, C. H. B., R. J. TAYLOR, 1972: On the assessment of surface heat flux and evaporation using large-scale parameters. Mon. Wea. Rev., 100, 81–92. The IDL script is annotated...
