Subject: | SGP/SIRS/E32 - Reprocessed: Partial shading |
DataStreams: | sgpsirsE32.b1, sgpsirs20sE32.a0
|
Description: | Shading of the PSP radiometer occurred after sunrise for a few minutes between 1215 and
1300 UTC affecting the downwelling_shortwave_hemisp variable as well as the associated min,
max, std, and inst measurements. The shading was caused by the presence of a narrow
antenna that was later relocated.
The data have been reprocessed to set specific affected periods to the missing_value
(-9999). Specific times affected were:
20120505: 1221-1229
20120506: 1230
20120509: 1233-1237
20120510: 1235-1239
20120513: 1243
20120514: 1243-1244 |
