Meteorological data:
| Measurement | Sampling Height | Averaging/Sampling Frequency | Investigator |
|---|---|---|---|
| Carbon dioxide (CO2) | 22, 100, 300 m | 15 min. | Arlyn Andrews |
| Carbon monoxide (CO) | 22, 100, 300 m | 15 min. | Arlyn Andrews |
| Met. data | 10, 100, 300 m | 1min. | Arlyn Andrews, Dan Wolfe |
| Ozone (O3) | 0, 300 m | 1 min. | Sam Oltmans |
| PFP flasks* | 300 m | about 12 flasks/week | various groups |
*PFP flasks are collected at tower and analyzed for numerous compounds by 3 groups:
1) GMD Carbon Cycle Group: CO, CO2, CH4, SF6, N2O, H2
2) GMD HATS Group:

Red means that these are newer compounds for us--any potential sampling or analysis artifacts have not been explored or characterized. For many of the compounds indicated in red text we do not have calibration scales (exceptions include propane, pentanes and acetylene)
