Daily
evapotranspiration values have been calculated for a
variety of crops grown in southern Alberta.
Climate data recorded from our IMCIN stations are
used in the calculations. Reference
evapotranspiration was calculated using the Penman
Montieth procedure as outlined in Food and
Agricultural Organization document, FAO 56.
Seasonal ET,
Precipitation, and Deficit values in millimetres,
are summarized for years 2002 to 2024 or starting
from the year of the IMCIN station installation.
Daily ET values are
available for alfalfa, grass, wheat, barley, barley
silage, canola, potato, sugar beet, dry bean, and
silage corn crops. An alfalfa reference ET is
also included. In 2022 two sites were relocated in an effort to elminate local interference; Enchant is now EnchantII and Bow Island is now Winnifred. A third site was recolated in 2023. The Iron Springs site is now the Picture Butte site.
***These data will be moving to the Alberta Climate Informatin Service (ACIS) in 2026. Please bookmark the following link for future access..
