In ASRCsoft/atmoschem.datasets: ASRC Atmospheric Chemistry Data Processing

These files contain the ASRC's routine meteorological and chemistry data from the Whiteface Mountain summit (WFMS), the Whiteface Mountain base (WFMB), Pinnacle State Park (PSP), and Queens College (QC) up to r Sys.getenv('processing_end'). Along with data from ASRC instruments, the dataset also includes data from the NYS Department of Environmental Conservation, the NYS Mesonet, and the EPA's Air Quality System.

The data has been processed to remove values that don't reflect ambient conditions, to adjust values for instrument calibrations, and to aggregate measurements to hourly values. All measurements are accompanied by flags following NARSTO guidelines (see https://cdiac.ess-dive.lbl.gov/programs/NARSTO/metadatastandards/consensus_flag_standard_20011105.pdf). Whiteface Mountain data before 2001 was not originally flagged, and M1 and V0 flags have been added retroactively. Queens College data is collected from the EPA's Air Quality System and updated on a different schedule than other sites.

WS_raw and WD_raw columns are raw averages of wind speed and wind direction measurements, respectively. These values are sometimes misleading and should be used with caution. All other WS and WD values are resultant wind speeds and directions.

Whiteface Mountain base CO measurements seem to be affected by room temperature and should also be used with caution.

The instruments.csv file contains instrument information for some recent data.

Any questions should be directed to Mr. William May at [e-mail] or Dr. James Schwab at [e-mail].
