Heavy rains caused flash floods along parts of the New South Wales coast in mid-February 2010, according to news reports. Measurements of rainfall over Australia in the second week of February, however, recorded the highest rainfall amounts over the country’s sparsely populated interior. This color-coded image shows total rainfall amounts from February 7 to 13, 2010. Light green indicates the lightest amounts (less than 50 millimeters, or 1.97 inches). Dark blue indicates the heaviest amounts (more than 450 millimeters, or 17.72 inches). Although areas of moderate rainfall extend throughout Queensland and New South Wales, the heaviest amounts appear in the northeastern corner of South Australia and along the borders with the other states.
This analysis is based on data from the Multisatellite Precipitation Analysis, which estimates rainfall by combining measurements from many satellites and calibrating them using rainfall measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite.
