Subject:	NSA/GNDRAD/C1 - Noisy PIR Data
DataStreams:	nsagndrad60sC1.a1, nsagndrad60sC1.b1
Description:	During the period referenced, the ground PIR was noisy in comparison to the the sky PIR data. (Note U021211.1 documents same problem for 9/1/98-2/28/99) The noise problem continued after the GNDRAD data logger was replaced in late September. Particularly strong examples of the noise can be seen in data from 11/10 - 11/19/99. The peak to peak noise reaches 12 W/m2.
Measurements:	nsagndrad60sC1.b1: PIR1 unshaded minimum(pir1_min) PIR1 unshaded maximum(pir1_max) PIR1 unshaded mean(pir1_mean) PIR1 unshaded standard deviation(pir1_sd) nsagndrad60sC1.a1: PIR1 unshaded standard deviation(pir1_sd) PIR1 unshaded mean(pir1_mean) PIR1 unshaded maximum(pir1_max) PIR1 unshaded minimum(pir1_min)
