   RH	changed from 1%RH to 0.01%RH
   tdry changed from .1degC to 0.01degC

Note that the increase in precision does not necessarily imply an increase
in accuracy.  Users are cautioned to continue to use their best scientific
judgement when using these or any other data.

NSA/MWRP/C1 - Reprocessed: Negative bias in LWP
DataStreams:nsamwrpC1.b1
Description:
After the radiometer was installed at the site following extensive refurbishing the 
retrieved LWP had a large negative bias (~-0.07 mm). The calibration coefficients were modified 
and that resolved the problem. Data for February, March and part of April were 
reprocessed with the revised calibrations and archived in July.

  • Water vapor, total precipitable, derived from Tbright using stat. retrvl.(totalPrecipitableWater)
  • Microwave brightness temperature(brightnessTemperature)
  • Liquid water path, from brightness temperatures using statistical retrieval(liquidWaterPath)

few hours.

NSA/MWR/C1 - High noise in 23.8-GHz channel
DataStreams:nsamwrlosC1.b1, nsamwrtipC1.a1
Description:
Starting approximately on February 13 the MWR experienced high level of noise in the 23.8 
GHz channel. The spikes became more prominent around Feb 17 and increased after that date 
as well. The cause of the interference was identified as the nearby MWRP on Oct 13 and 
the instruments were realigned.

NSA/SONDE/C1 - Wind data missing
DataStreams:nsasondewnpnC1.b1
Description:
A GPS problem associated with Vaisala BBSS ground station software issues caused the 
ground stations to enter into an error state when using GPS wind finding. In some instances, 
the flight was aborted due to the error state and not data was collected.  A workaround 
was developed to allow sondes to be launched without collecting wind data.

NSA/SONDE/C1 - Wind data missing
DataStreams:nsasondewnpnC1.b1
Description:
After some power disruptions, the Power Supply board of the SPS220 ground station was 
damaged.  The damage caused the supply to not have enough power to run the GPS board.  
Switching to the back up DigiCora II did not alleviate the problem as the fix for GPS failure 
to all Vaisala sonde products had not been installed.  A different P/S was found and sent 
up to replace the failed one.

NSA/MWRP/C1 - Reprocess: V-band channels too cold
DataStreams:nsamwrpC1.b1
Description:
The calibrations of 7/20 and 7/29 were slightly affected by high humidity at the site. As 
a result the V-band channels were calibrated too cold.
On 8/26 I modified the mp.cfg file and reinstated the calibration coefficients derived on 
3/20/2009.

Data between 7/20 and 8/26 will be reprocessed with one set of calibration coefficients.
Measurements:nsamwrpC1.b1:
  • Temperature, virtual, vert. prof. sfc-10km, fr. wtr. vap. dens. and temp. prof.(virtualTemperature)
  • Air temperature(temperature)
  • Microwave brightness temperature(brightnessTemperature)
