NASA has produced a couple of articles in the last few weeks demonstrating how Earth Observation (EO) data can help monitor both ends of the temperature spectrum. Beginning with the heat, they’ve produced a map of all the fires detected … Continue reading
We’re so used to seeing headlines about humans destroying the rainforests, swaths of deforestation and our activities affecting the climate; seeing a report suggesting we are making the planet the greener caught our attention. ‘China and India lead in greening … Continue reading
Everyone knows the British like to talk about the weather. But last week even NASA was talking about the British weather – so you know something must be happening! Well, it’s been hot. Now I know many readers from other … Continue reading
Last week’s eclipse gave an excellent demonstration of the sun’s role in optical remote sensing. The image to the left was acquired on the 21st August by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the NOAA/NASA Suomi NPP satellite, … Continue reading
Algae have been making the headlines in the last few weeks, which is definitely a rarely used phrase! Firstly, the Lake Erie freshwater algal bloom has begun in the western end of the lake near Toledo. This is something that … Continue reading
The titular paraphrasing of the famous falling tree in the forest riddle was well and truly answered this week, and shows just how far satellite remote sensing has come in recent years. Last week sometime between Monday 10th July and … Continue reading
Spatial resolution is a key characteristic in remote sensing, as we’ve previously discussed. Often the view is that you need an object to be significantly larger than the resolution to be able to see it on an image. However, this … Continue reading
Monitoring fires from space has significant advantages when compared to on-ground activity. Not only are wider areas easier to monitor, but there are obvious safety benefits too. The different ways this can be done have been highlighted through a number … Continue reading
If you’d like the 2017 update, please click here. Earth Observation (EO) satellites account for just over one quarter of all the operational satellites currently orbiting the Earth. As noted last week there are 1 419 operational satellites, and 374 … Continue reading
Monitoring forest biomass is essential for understanding the global carbon cycle because: Forests account for around 45 % of terrestrial carbon, and deforestation accounts for 10% of greenhouse gas emissions Deforestation and forest degradation release approximately identical amounts of greenhouse … Continue reading
