 Decided to make a LAI measurement this morning since there was good cloud cover. While making the measurements the skies started clearing so this data set, 6/23/13, should be used with caution.

Below is a table of when LAI-2000 measurements were taken on the tower.

  1. Attached is the text file from Ned which downloaded the LAI-2000 values.  I still don't have the processed LAI numbers from this file, however...
