Climate Monitor

"Better information drives better management decisions"


The Queensland Governments Drought and Climate Adaptation Program (DCAP) is helping the horticulture and agriculture industries across Queensland through research, development and extension activities. DCAP aims to help producers better manage drought and climate impacts.

Climate Monitor allows the user to analyse and graph minimum and maximum temperature and rainfall for all available years, calculate thermal time (chill and heat units) and be able to retrieve, analyse and graph temperature thresholds (for a chosen location).

These climate variables are critical drivers of product quality and income potential. This location specific climate analysis capability is equally valuable to broadacre cropping (e.g., sorghum, wheat, chickpeas, cotton), cattle operations and horticultural businesses, where knowledge of planting windows (maximum and minimum temperature) as well as heat stress factors are major drivers of potential yield, sustainability and profit.

This unique analysis tool will allow horticultural business managers to refine and improve their business decisions around crop choice, variety, planting dates and location, and to maximise their chance of harvesting a high-quality crop, by identifying their optimum crop growth time slots.

Climate Monitor allows improved, detailed location specific (5km grid) climate analysis, supporting and under-pinning better, more informed management decisions.

Business owners and managers can use Climate Monitor to plan and prepare based on location specific comparisons of climate records and the current BoM seven-day forecast data, with historical “norms”.

Climate Monitor allows you to easily review if and how climatic conditions have changed at your chosen production location over time. Users can also research alternate “ideal” production locations and times elsewhere in Australia, based on their crops’ “ideal growing conditions”, and potentially move, modify or expand their production footprint to maximise product quality and supply continuity.

How to use Climate Monitor

User guide with examples

Climate Monitor allows you to select one or more stations and/or grid cells up to a maximum of 3. Locations can be selected first or added to existing analyses.

  1. Selection a location or multiple locations
  2. Select one or more stations (blue circles) or click anywhere there is not a cicrle. The latter selects from the 5 km grid and a blue marker is shown, click the marker if you are satisfied it is in the correct place and it will be shown as a red dot.

    Up to three stations and/or grid cells can be selected.

  3. Click Temperature menu item and then Historical or an analysis or click Rainfall and Evaporation. Rainfall and evaporation options are currently limited to Historical analyses
  4. Historical

    Additional Information on methods used

Use the map on the right to select a station or narrow down the search area by typing a partial name (case doesn't matter) for the station of interest.

Only stations that record temperature are shown.

Alternatively, select a grid cell.

Chilling

  • Chill Hours
  • Calculated as the number of hours where the temperature is greater than 0ºC and less than 7.2ºC, see Bennet (1949) and Weinberger (1950).

  • Chill Portions
  • Calculated using the methodology of Erez et al. (1990)

Growth Potential

  • Growing Degree Days
  • This has been calculated as the average daily temperature minus the base temperature (Tbase)

  • Growing Degree Hours
  • calculated using the metholodology of Anderson et al. (1986) using the ASYMCUR model
