ENA/MWR3C/C1 - Reprocessing Notice (RID 1134)
DataStreams:enamwr3cC1.b1
Description:
See below for details of reprocessing that was completed on 20140902.  Original DQR 
category: 4 (Red, Incorrect).

-----------------------------------------------------------

Occasionally the brightness temperatures drop to zero. The problem was identified with 
occasional missing lines in the raw data.
Measurements:enamwr3cC1.b1:
  • Column precip water vapor(pwv)
  • 23.8 GHz sky brightness temperature(tbsky23)
  • Mean 31.4 GHz sky brightness temperature(tbsky31)
  • 90.0 GHz sky brightness temperature(tbsky90)
  • Liquid water path best-estimate value, hourly mean(lwp)

ENA/MWRP/C1 - Bad calibration
DataStreams:enamwrpC1.b1
Description:
The radiometer was poorly calibrated following a power outage at the site.
Measurements:enamwrpC1.b1:
  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
  • Temperature, virtual, vert. prof. sfc-10km, fr. wtr. vap. dens. and temp. prof.(virtualTemperature)
  • Microwave brightness temperature(brightnessTemperature)
  • Temperature at the ground station(temperature)
  • Height, level of free convection(levelFreeConvection)
  • Density, water vapor, prof. from sfc.-10 km, der. from Tbright stat. retrvl.(waterVaporDensity)
  • Humidity, relative, prof. from sfc.-10km, from water vap. dens. and temp. prof.(relativeHumidity)
  • Liquid water content, cloud, vert. prof. sfc.-10km, from Tbright stat. retrvl.(liquidWaterContent)
  • Mixing ratio, water vap., vert. prof. sfc-10km, frm retr. water vap. dens. prof(waterVaporMixingRatio)
  • Liquid water path, from Tbright at 23.835 and 30.0 GHz only, using stat. retrvl.(liquidWaterPath2)
  • Liquid water path, from brightness temperatures using statistical retrieval(liquidWaterPath)
  • Water vapor, total precipitable, derived from Tbright using stat. retrvl.(totalPrecipitableWater)

ENA/MWRP/C1 - Reprocess: Calibration drift
DataStreams:enamwrpC1.b1
Description:
The data are incorrect mostly because of fast drift in the calibration. Brightness 
temperatures become negative after 9/7/2015.
Measurements:enamwrpC1.b1:
  • Water vapor, tot. precipitable, from Tbright, 23.835 & 30.0 GHz, stat. retrvl.(totalPrecipitableWater2)
  • Microwave brightness temperature(brightnessTemperature)

Subject:
ENA/C1 - Reprocess: Slightly incorrect location fields
DataStreams:enamwr3cC1.b1
Description:
Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt 
instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be 
corrected. The respective GRW and ENA lat, lon, and alt values are as follows:
 
GRW  lat = 39.0911 ;
ENA lat = 39.0916 ;
GRW  lon = -28.0297 ;
ENA  lon = -28.0257 ;
GRW  alt = 26 ;
ENA  alt = 30.48 ;
Measurements:enamwr3cC1.b1:
  • North latitude(lat)
  • Altitude above mean sea level(alt)
  • East longitude(lon)
