What is Climate Diary?

Climate Diary is a mobile App which integrates users’ important climate and farm data presenting current status and historical patterns to inform management decisions. Data is synchronised across devices and is checked daily on a server, with warnings of critical events sent to users via SMS and email.


Climate Diary can connect to a wide range of public time-series data sources, commercial weather stations, crowd-sourced shared data, personal file-based data, and manually entered data.

The software is designed to handle rainfall, temperature, heat-sums, evaporation, soil-moisture, humidity, solar radiation, crop water use, stream flow, drought-indices, storage levels, atmospheric and ocean data, wind speed, and any customised time- series data.


Climate Diary presents current-status summaries while letting users explore each time-series through innovative calendar, graphical and reporting tools.


Climate Diary will be released through the Apple and Google App Stores with an initial cost of AU$4.95. This will provide a user with up to 5 data sources. Annual subscription services will be made available to add more data-sources and enhanced functionality (including real-time alerts and updates), ranging between AU$10 and $1000 per year.


Climate Diary is currently being developed for iOS, Android and the web by DHM software. It will initially be released for Australian users, with future plans to release to overseas countries such as the US, UK, France and throughout SE Asia. Each country will present its own development challenges as government meteorological organisations have different formats and access rules for their data. DHM will be seeking partners to help develop the functionality for these countries.
