NOAA/ESRL operates staffed atmospheric baseline observatories from which numerous in situ and remote atmospheric and solar measurements are conducted. The overall scientific programs and administrative functions of the observatories are handled from Boulder with on-site station chiefs caring for day-to-day station activities.
