Subject: | GRW/MWR/M1 - Incorrect instrument computer set-up |
DataStreams: | grwmwrtipM1.a1, grwmwrlosM1.b1
|
Description: | Starting late on 07/11 the instrument began to have very brief (< 1 min) data outages
every few hours. By 07/12 data had become noticeably incorrect, particularly the PWV, LWP,
TB23, and TB31. At ~17 Z on 0713 the missing data / no data available flags became more
frequent.
The problem was identified as improper settings of the instrument computer and was solved
on 8/9. |

Subject: | GRW/MWR/M1 - Erratic brightness temperature |
DataStreams: | grwmwrtipM1.a1, grwmwrlosM1.b1
|
Description: | Around 12 Z on 7/20 both the PWV and 23.8 GHz brightness temp values began to diverge from
those of the MWRP. By 7/22 both the LWP and 31.4 GHz brightness temp had followed suit.
At 0600 Z on 7/22 multiple (10-20), brief (<=1 min) data outages began appearing hourly.
The problem persisted intermittently until 8/9.
On 8/9, changes in the settings of the computer restored the proper functionality of the
MWR software. |

Subject: | GRW/MWRP/M1 - Reprocessed: Updated calibration coefficients |
DataStreams: | grwmwrpM1.b1
|
Description: | On 9/8/2010 the calibration of of the K-band channels was updated. This caused a slight
decrease of the retrieved liquid water path.
Updated calibrations have been applied to data from 7/1-9/8. The LWP was decreased
slightly as a result of the recalibration. Reprocessed data were archived in November 2010. |

- Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
- Water vapor, total precipitable, derived from Tbright using stat. retrvl.(totalPrecipitableWater)
- Liquid water path, from brightness temperatures using statistical retrieval(liquidWaterPath)
- Liquid water path, from Tbright at 23.835 and 30.0 GHz only, using stat. retrvl.(liquidWaterPath2)
- Liquid water content, cloud, vert. prof. sfc.-10km, from Tbright stat. retrvl.(liquidWaterContent)
