Subject: | SGP/IRT10m/C1 - Reprocess: IRT insufficiently insulated |
DataStreams: | sgpirt10mC1.b1 |
Description: | The upwelling IRT on the 10m tower was insufficiently insulated to maintain an internal reference temperature above 0 degrees C. Measurements of surface 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 ambient temperature (e.g. inst_up_long_hemisp_dome_temp or inst_up_long_dome_temp from SGP.E13 SIRS) |

Subject: | SGP/IRT/C1 - changed output range for new datalogger |
DataStreams: | sgpirt10mC1.a1, sgpirt10mC1.b1 |
Description: | The tower was lowered and the analog output parameters were changed at 14:45 to compensate for the recent change in data acquisition from an MFR logger to a CR10X. |
