NASA's Earth Observatory has released satellite pictures showing the greening effect of recent flooding on western and north-western Queensland.
Key points:
- 1. NASA's MODIS spectroradiometer produces false-colour images that differentiate between water, vegetation and bare land
- 2. Recently released images show floodwater from northern Queensland has worked its way south into Channel Country
- 3. Parts of the state remain flooded, with towns becoming isolated and groceries having to be flown in to Bedourie by passenger plane
The pictures, taken using NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) mounted on its Terra satellite, show water flowing into parts of the state that were bone-dry just a month and a half ago, bringing with it increased vegetation.
While pictures generated by spectroradiometers are rendered in false colour, due to the instruments' ability to measure properties of light far beyond what the eye can see, the blue sections do still represent water, while the green sections represent vegetation and the brown sections arid brown land.
Northern Queensland has experienced extensive rain over the past month, with some areas reporting well over 300 millimetres in 24-hour periods. Read More…
