Subject: | NSA/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry |
DataStreams: | nsasondewnpnC1.b1 |
Description: | The output precision of the following variables was increased 20060929: 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: | NSA/MWR/C1 - RFI screening test |
DataStreams: | nsamwrlosC1.b1, nsamwrtipC1.a1 |
Description: | The instrument was covered with a shield to test the effect on the RF interference that is affecting the measurements since February. The test was performed on 4/15 and 4/16 for a few hours. |

Subject: | 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. |
