GRW/SKYRAD/M1 - Possible dirty dome

The difference between downwelling shortwave hemispheric irradiance and derived 
downwelling shortwave hemispheric irradiance was larger than normal (>50W/m2) and was most 
noticeable at lower zenith angles.  The problem spontaneously resolved itself on 7/16 without any 
specific callouts by the GRW cleaning personnel on their reports.  Short_direct_normal 
datastream is suspected to be low due to potentially dirty NIP instrument window during 
this time period.  The commencement of this problem corresponds with a rain event early 
7/12. The possibility of other radiometers affected by dirty domes is also possible. 
Longwave instruments are typically immune to this level of contamination.

GRW/ECOR/M1 - Effects on ECOR CO2 Flux and Concentration by Aircraft

Aircraft landings, departures, and running aircraft on the airport pad were found to 
produce spikes in the half hourly CO2 flux and small spikes in CO2 concentration on many days 
during the entire deployment of the AMF1 at GRW. This influence sometimes occurred 
multiple periods in a day; this was typical of the year of data.  The spikes range from only 
several micromoles s-1 m-2 to one hundred or more for flux (a typical spike was in the 
twenties) and near zero to 1.0 mmoles m-3 for CO2 concentration (typically around 0.15).

Occasionally an influence on water vapor density was detected, but this was fairly rare 
and usually of very small magnitude.
