Campaign Forecast for the period Friday 15/1 to Tuesday 19/1 issued Friday 15/1 8h

>From Meteo France by default, in brackets (from GSF)
The weather in the next days is influenced by a low pressure system over Island, a low pressure system moving eastwards from Spain to Genoa (inducing variable winds over France), and a ridge of high pressure which can be form between the East European high and the Azore high, and that can induce light winds over Paris. Temperature will keep mild. Precipitation.

Friday 15/1 :
T max 5°C, partially sunny to cloudy Very light surface winds (10 km/h) in variable directions; changing from W in morning to S in afternoon; Surface PM2.5 ~ <50 µg/m3, POA < 20 µg/m3 at 18 UT , plume in Eastern sector, interesting day ! - Suggestion MOLA plume measurements in E-NE sector, at a central angle of 70°, which best should capture wind direction change during the day; - MAXDOAS circular pattern at the edge of the agglomeration (will there be HCHO build-up?)
Saturday 16/1 :
T max 7°C, cloudy, rain in the afternoon Moderately strong surface winds (20 km/h) from SE morning to E afternoon; Surface PM2.5 < 30 µg/m3, POA < 15 µg/m3 , plume in NW sector, turning to N in ther afternoon
