The weather station is located on the roof of the NCAR Foothills Laboratory in North East Boulder, Colorado. The data is accurate for that location but the location is not perfect for meteorological data gathering. Wind speeds at this elevation may be higher than at ground level and there may be some wind shading due to other tall buildings in the vicinity. On days with no wind, the temperature may be artificially high due to heating of the roof. Finally, the RAINCAP sensor measures the momentum of precipitation, which is reliable for rain and to some extent hail, but not for snow, fog, dew, etc. This data is provided for non-scientific use as a public service to the community. NCAR and UCAR hold no responsibility for the accuracy of the data and bear no liability for the use of the data presented on these web pages.
