Description: | Subject: BSRN Data Release (July 15 - July 19, 1994)

Telephone: (303) 497-7315
Institution: SRRB\NOAA
Platform/Measurement: BSRN Pyranometer (PSP1) shadearm off
alignment and NIP not tracking.
what level data: a1
period of time in question
start: July 15, 1994 at 00:00:00 (GMT)
end: July 19, 1994 at 23:59:59 (GMT)
Data should be labeled:
-Calculated Global irradiance could be labeled
"incorrect".
- NIP not tracking correctly
Discussion of Problem:
1. The shadearm on the Pyranometer (PSP1), calculating diffuse
irradiance, was off alignment (power outage).
Use this algorithm to pick out the times that the
shadearm is off of alignment.
(PSP2-(NIP*cosine of zenith angle))/PSP1 < .90
2. NIP tracker was down because of power outage.
Other observations/measurements impacted by this problem:
* Calculated Global Irradiance and Diffuse Irradiance
* Direct Normal Irradiance measurement is Wrong
Suggested Corrections of the Problem: None
REQUIRED ACTIONS:
This report is informational no further action required
