Climate Metrics Glossary
This is the glossary of a selection of important data ‘Parameters’ used in IrriWatch. The parameters are categorised into Irrigation, Crop and Climate. The descriptions include an explanation of the parameter, a description of why it is useful as well as a possible example on how to use it.
This section covers the Climate and Weather Metrics.
Air Temperature Daily (°C)
Daily air temperature for specifying local weather conditions.
Weather conditions affects various biophysical processes such as Evapotranspiration, crop growth and carbon storage in the soil, among others. In combination with relative humidity, it will help understanding daily variability of various crop bio-physical processes, in particular heat and VPD (vapor pressure deficit) stress.

Cumulative Growing Degree Days or Units GDD (or GDU)
The measure of heat accumulation by the crop from its planting date. It is often used to predict the phenological stages (the timing of life cycle events in plants) of a crop and when the crop reaches maturity.
Min. Air Temperature (°C)
This is the minimum air temperature that occurs during a day. The air temperature is measured hourly by a global weather model.
The minimum air temperature allows to detect a cold wave or frost that sometimes can have direct impact on flowering or other stages of the plant. Minimum air temperature can also help detecting extreme weather events (an interesting parameter for crop insurances).
