I really need to obtain the daily-air temperature for several months of 2011. In addition, the data I'm looking for must have the maximum spatial resolution of 1Km*1Km. Since, as I know, there isn't any reliable method to estimate air temp. from satellite imagery, I have to get the data from weather stations available on the internet. However, I haven't found any sites to help me what I need.
Does anyone know how can I get the data for Australia?
