Central Valley Hydrologic Model version 2 (CVHM2): Tidal Data

These data show monthly mean sea level for the San Francisco Bay from July 1854 through December 2021. This dataset is a compilation of two locations since one location had a shorter record: the Alameda (Naval Air Station) station was used from April 1939 through December 2021 while the San Francisco station was used from July 1854 through March 1939 [Holgate and others (2013); PAMSL (2018)]. The Alameda gauge was used when these data were available due to its location being further east in San Francisco Bay and therefore a better fit for the updated Central Valley Hydrologic Model (CVHM2). The San Francisco station is located just east of the Golden Gate Bridge at 37.806667°, -122.465° while the Alameda station is southeast of the Bay Bridge at 37.771667°, -122.298333°. These data are important for establishing the boundary conditions for CVHM2, especially as the sea level rises.
