![]() Growers using data from the Murraylands and Riverland Landscape Board’s weather station network can follow the notifications under the ‘harvest’ tab for each station or contact Jeremy Nelson for support on 0439 591 826. Lower Atmospheric Stability (Haines) Index. People seeking more information about the use of Aurora can refer to the CFS website’s grain harvesting section. In the meantime, farmers and contractors will need to use the Aurora system and adhere to the GFBI ratings. A Grain Harvesting Operations Table is still in development and will use a similar table to the earlier Grain Harvesting Code of Practice. The former Grasslands Fire Danger Index (GFDI) has now been phased out in favour of the new Grasslands Fire Behaviour Index (GFBI). “The Aurora system has been endorsed by the CFS and the new Grain Harvesting Code of Practice as a reliable means to rate conditions against fire risk during harvest periods,” he added. “The calculator is easy to use and can be saved as on the home screen of your smart phone for quick and easy access” This platform should be regularly consulted to make sure that harvest operations are only undertaken when the Grasslands Fire Danger Index is below 40”. The Aurora calculator has been developed to provide localised estimations of grassland fire risk. “It is essential that grain growers, employees and contractors are aware of the recent revision of the Grain Harvesting Code of Practice (GHCoP). This tool allows you to compute standard fire weather index values from the Canadian Forest Fire Danger Rating System. The amount of water in upper soil layers. The reference tree family used for the FWI is a pine with coniferous litter on a raw humus ground. Snow cover is also taken into account in estimating hazards. Jeremy Nelson, a Sustainable Agriculture Project Officer with the Murraylands and Riverland Landscape Board, said that it was important for growers to ensure that harvest operations are carried out in line with the Grasslands Fire Behaviour Index generated by the Aurora Fire Behaviour Calculator this harvest. The Fire Weather Index (FWI) is based on midday air temperatures, relative air humidity and wind speeds as well as 24-hour precipitation rates. Harvest operations must cease when the Grasslands Fire Behaviour Index rating reaches 40. ![]() The Aurora Fire Behaviour Calculator produces a Grasslands Fire Behaviour Index (GFBI) which uses local temperature, humidity and wind speed information to produce a fire danger risk rating.
