-> Data

- Pb210_2sites.csv contains daily 210Pb observations at Helsinki and Sodankyla in the period January-March 2003. Dates are in "m/d/yyyy" format and 210Pb measurements are in µBq/m³.

Please refer to Mattson et al. (1996) for details.

-> Model output

- trac_avg.merra2_2x25_RnPbBe.200301-200303-monthly-means.bpch.gz: contains model output of monthly mean 210Pb and 7Be concentrations for January, February, and March 2003.

- ts_1h.200301.bpch.tar: hourly model output for January 2003

- ts_1h.200302.bpch.tar: hourly model output for February 2003

- ts_1h.200303.bpch.tar: hourly model output for March 2003

- diaginfo.dat, tracerinfo.dat: information data files needed for the GAMAP package (in IDL) used to read and process the model output. GAMAP is publicly available at: http://acmg.seas.harvard.edu/gamap/
