Subject: | NSA/SKYRAD/C1 - IRT removed for repair |
DataStreams: | nsaskyrad60sC1.a1, nsaskyradC1.00 |
Description: | The instrument was damaged by internal water condensation caused by the exterior foam insulation used to keep the IRT above freezing. It was returned in July 1998 to the manufacturer for repair. |

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) |
