Subject: | SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | The output precision of the following variables was increased 20060928 alt changed from 1m to 0.1m dp changed from 0.1degC to 0.01degC pres changed from 0.1 hPa to 0.01 hPa 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. |

Subject: | SGP/MWR/C1 - Increased noise in 31.4 GHz channel |
DataStreams: | sgpmwrlosC1.b1, sgpmwrtipC1.a1 |
Description: | The 31.4 GHz channel has been showing an increased level of noise which results in increased noise in the LWP retrievals. The instrument is tipping and all other parameters seem to be in the range. The elevate noise started in May, but it seems to have become slightly worse after summer. After November the noise level seems to have gone back to normal. |
