Subject: | NSA/SKYRAD/C1 - IRT measurements during precipitation events |
DataStreams: | nsaskyrad60sC1.a1 |
Description: | The IRT measurement of sky/cloud temperature was in question during precipitation events because rain or snow could accumulate in the upward-pointed lens barrel. This was corrected by reorienting the IRT to measure the sky temperature as reflected by a gold mirror. |

Subject: | NSA/SKYRAD/C1 - Reprocess: IRT insufficiently heated |
DataStreams: | nsaskyrad60sC1.a1 |
Description: | IRT had insufficient heating to maintain an internal reference temperature above 0 degrees C. Measurements of sky temperature were over-estimated when instrument was below freezing. Data will be reprocessed, but users can correct data using the following correction factor: If T_reference < -5?C, then IRT_corrected = (IRT_original - 32.993K)/0.87238 where T_reference can be estimated with the ambient temperature (e.g. inst_down_long_hemisp_dome_temp or inst_down_long_dome_temp) |
