HISTORICAL INFORMATION

The following documents contain evapotranspiration data and rainfall data for our weather stations on the East and West side of Santa Rosa. The document is separated into three sections:

Reference Evapotranspiration (ETo) Data in inches, which displays reference evapotranspiration rates for cool season turf 4 to 6 inches tall, well watered, and densely planted in large pastures.

Rainfall Data in inches, which displays rainfall data collected at the Laguna Wastewater Treatment Plant in Santa Rosa. 

ETo in inches Minus Effective Rainfall in inches, which combines the data of the first two tables. Because not all rainfall received is useful to plants, rainfall data has been adjusted to account for this. That is why the title of this table refers to "effective rainfall".
