TWP/SKYRAD/C2 - Downwelling LW #1 questionable

Hemispheric downwelling measurements on the hemisp1 were suspect due to the large 
differences between PIR1 and PIR2 (i.e. greater than 10W/m2). Maintenance on 3/14/2012 indicated 
problem with the connector and ops re-seated the connector on PIR 1. After the 
maintenance, PIR1 and PIR2 returned to tracking each other within 10W/m2 as typical.

Use PIR2 (down_long_hemisp2) data for the specified period.
