ARIM jNO2 Filter Radiometer			
BEACHON 30 m tower, measured downwelling and calculated total jNO2			
Total jNO2 is calculated by scaling the downwelling jNO2 by a factor of 1.05,			
determined by using the upwelling to downwelling ratio measured from the tower on 8/10/2010	
Measurements taken from top of BEACHON 30 m tower, or from top of trailer (approximately 3 m above ground level), or from lift, as indicated in file name.
