Every month or so, NASA Earth Observatory will offer up a puzzling satellite image here on Earth Matters. The first one is above. Your challenge is to use the comments section below to tell us what part of the world we’re looking at, when the image was acquired, and what’s happening in the scene. How to answer. […]
Here at the Earth Observatory, we sift through a constant stream of data and imagery that flows in from a range of satellite, airborne, and ground-based sensors. As a result, the images we share on our website really run the gamut. Many are true-color images that look like what your naked eye would see if […]
Eni Njoku We’ve been rained out for four straight days Friday through Monday due to unstable weather conditions in the area – not exactly what we expected! On the other hand we should certainly observe some pretty wet fields when we make our next PALS flights. On Saturday things looked good in the early morning […]
Here at the Earth Observatory we know as well as anybody that explaining the nuance and complexity of climate modeling isn’t easy. In May, Nature Climate Change published a study pointing out that the number of news articles that mention climate change has been declining since 2007. There was a slight increase in mentions following […]
Andreas Colliander Below are quick-look images from yesterday’s first science flights (June 7). A single polarization each of the radiometer and radar are shown. The data are from high-altitude lines 3 through 8 (lines 1 and 2 were not acquired). For reference, the study site map is also shown (at right). The radiometer brightness temperature […]
Mike Cosh June 7th was our first day of soil moisture sampling in the SMAPVEX12 experiment after two days of training and rehearsal. Beginning at 6:45am, 13 soil moisture teams set out to record surface soil moisture at 59 fields. By 2pm, the teams had returned successfully measuring moisture at 53 fields. For more […]
Eni Njoku Today was planned as the first full day of science flights and soil moisture sampling. The morning Go/No-Go telecon confirmed our “Go” decision of yesterday evening, so the ground sampling crews were given the signal to head for the fields (an hour or more drive from Winnipeg) and the PALS folk headed for […]
Eni Njoku Today was a test day, to go through the PALS/Twin Otter flight operations, and for the ground teams to get familiar with the soil and vegetation sampling equipment and the field site locations. Test Flight We were at the airport by 8 am. The plane was outside being prepared by Richard and Dave […]
The Earth Observatory image of the day for June 5 shows flooding in Botswana’s Savuti River and Savuti Swamp. The abundant water turns out to be a very small part of a much bigger picture. The Savuti Swamp sits within the Kalahari Desert, which stretches across Namibia, Angola, Zambia, South Africa, and most of Botswana. More […]
