Supporting Data for Hydrologic Studies in San Francisco Bay, California: Meteorological Measurements at the Port of Redwood City, 1998-2001

By Laurence Edward Schemel


Meteorological data were collected during 1998-2001 at the Port of Redwood City, California, to support hydrologic studies in South San Francisco Bay.  The measured meteorological variables were air temperature, atmospheric pressure, quantum flux (insolation), and four parameters of wind speed and direction: scalar mean horizontal wind speed, (vector) resultant horizontal wind speed, resultant wind direction, and standard deviation of the wind direction.  Hourly mean values based on measurements at five-minute intervals were logged at the site.  Daily mean values were computed for temperature, insolation, pressure, and scalar wind speed.  Daily mean values for 1998-2001 are described in this report, and a short record of hourly mean values is compared to data from another near-by station.  Data (hourly and daily mean) from the entire period of record (starting in April 1992) and reports describing data prior to 1998 are provided.

Data Updates

The meteorological station at the Port of Redwood City has been dismantled, and collection of meteorological data for South San Francisco Bay has been moved to the Dumbarton Bridge monitoring site (see for posting of subsequent data). Meteorological data for the Port of Redwood city extend from April 10, 1992 to October 17, 2006. Important details concerning these data are contained in the reports available here and in text files included with the annual data updates.
