When You Open Files Using Excel 2000 or 2003 The first thing you will need to do is check your Excel macro security. To do this, go to Tools → Macros → Security. Make sure you choose the “Medium” option. This will allow you to choose whether or not to run a Macro when you download it. After this, you will probably want to change the setting back to the original.
When You Open Files Using Excel 2007…
MT-CLIM
MT-CLIM Inputs Basic climate data Maximum daily air temperature Minimum daily air temperature Daily precipitation
MT-CLIM
MT-CLIM Outputs Calculated for a given site, or for another site using a “base station” Required for Biome-BGC Daytime average air temperature Daytime average vapor pressure deficit Incoming solar radiation Daylength
Daylength Calculation Based on Latitude
