Past Methods (No longer in use)
- Dry deposition samples and meteorological mea
Started: 1992-08-11
Ended: 2000-05-20Accumulated weekly dry deposition samples collected on filter packs. Continuous meteorology averaged hourly and quarter hourly. Measurements include: wind speed, direction and direction variance; ambient temperature, relative humidity, surface wetness; precipitation (heated tipping bucket collector), total irradiance; total fine particulate mass; SO2 and HNO3 vapor, SO4 and NO3 particulate.
