Contra Costa Rain Gauge DataBelow is link to a HEC-DSS file that contains much of our rainfall data. Where we have real time data (time stamped at each tipping bucket rain gauge tip) we provide data at 5 minute intervals. Where we have only 1 hour or 1 day data, we provide data at 1 hour or 1 day intervals. You will need HEC-DSSVue to view the data after unzipping the file. Not all of our data is in this DSS file. We are continuing to add data to it.
(DSS file 3.9 MB updated 6/18/2012 -right click to download file) Data is in inches, is provisional and subject to revision. The data is current as of June 30, 2011).
So that they would be flagged as missing, but would not skew the data plots in DSSVue, missing data has been set to equal -0.09999. Use the HEC-DSSVue Tools>Math Functions>General tab>Replace Specific Values pull down menu to change these.
