     SHAND RECORD    2001,99,1000    -   PRESENT

Legit Gaps:

 2010-08-10 13:00 to 2011-1-14 12:00    (missing from direct downloads and didn't see it in shand record either... I think due to 5 min snow)

Imperfect Outline of Array IDs (work in progress)

 2001 - 2011: 123 = Met, 17 elements
 2011 to present: 127 = Met, 17 elements

 2001 - 2007:  228 = Soil, 25 elements
 2007 - 2011: 227 = Soil, 25 elements
 246 = Soil, 25 elements
 247 = Soil, 25 elements  

 402 = MRC Probe (bunk values), 13 elements
 404 = MRC Probe (resistances), 13 elements
 

A couple ways to count elements;

$ grep "^234" c1_grid_2009_08_04.dat

copy the result.  Fire up python and then a="result" len(a.split(',')
