Automated readings from the rain gages throughout the city. These rain gages use 'tipping buckets' to measure rainfall; whenever the 'bucket' tips, the incremental rainfall data are recorded. Because of this measurement system, this dataset is only updated when there are new 'bucket tips'; the system searches for new data several times an hour, but only updates this dataset if there are new records. The data rate is limited, so for heavy rainfall there will be multiple 'bucket tips' in one record.
