Subject: | HFE/SKYRAD/M1 - IRT bias |
DataStreams: | hfeskyrad60sM1.b1 |
Description: | The sky temperatures exhibited a positive bias compared to AERI, especially when < 230K. This is indicative of an incorrect emissivity setting (to compensate for the gold mirror) or a poor calibration. A similar problem with the same instrument occurred during the FKB deployment that was attributed to water vapor. |

Subject: | HFE/VCEIL/M1 - Reprocess: Incorrect serial_number and sum_backscatter fields |
DataStreams: | hfevceil25kM1.b1 |
Description: | Attribute serial_number: In most cases, this field is not representative of the actual serial number of the instrument because the value did not change when an instrument changed locations or was replaced with a spare. Variable sum_backscatter: An out-of-range condition for the "sum of detected and normalized backscatter" was reported as 0 instead of missing (-9999). The valid range is 0 - 0.0999 /srad. |
