Our Services

COtL offer a unique set of skills:
  • Establishment of weather monitoring networks (‘mesonets’).
  • Ongoing operation, maintenance and management of weather monitoring networks:
    • Particular expertise in regard to mesonets for spray drift management including:
    • Detection of hazardous and non-hazardous spray conditions (including hazardous and non-hazardous inversions).
    • Estimation of hazardous and non-hazardous inversions via machine learning.
    • Forecasts of hazardous and non-hazardous inversions.
    • Liaison with various agricultural grower groups.
  • Partnerships with academic and research organisations.

Observations Provided


The COtL Mesonet can accommodate an in-depth range of different observations from many types of sensors. The data updates every 10-minutes with lengthy data histories accumulating at each station. Our current networks monitor the following:
  • Hazardous Inversions
  • Temperature
  • Relative Humidity
  • Barometric Pressure
  • Wind Speed and Direction at 2m
  • Wind Speed and Direction at 10m
  • Vertical Temperature Difference (10m – 1.2m)
  • Rainfall (tipping bucket)
  • Solar Radiation

From these sensors, a range of useful metrics can be determined such as:
  • Grass Fire Danger Index (GFDI), FBI, and Grain Harvesting Code of Practice values (GHCoP)
  • Dew Point
  • Delta-T
  • Wind Gust speeds (at 2m and 10m)
  • Frost metrics (i.e. time below minimum temperature threshold)
  • Daily/Monthly/Yearly rainfall
  • Crop Science (i.e. degree growing days, crop phenology)
  • Crop Pest/Disease Risks
  • Livestock Comfort Risks
  • Machine learning 2-hour predictions
Our stations are configured such that different sensors can easily be added in future, such as soil moisture loggers and other sensors.
