NASA's Space Radionometer (NASA) Space Astronomy Experiment (ECOSTRESS) aims to study how plants respond to heat and water stress by measuring the temperature of the earth's vegetation at every minute of the day, with an accuracy of a few tenths of a degree.
Unusual warmth, in addition to botany, can be a warning sign of important changes and concerns in many areas of research. Here are four other areas where the accurate temperature measurements of ECOSTRESS could make a difference
The ECOSTRESS radiometer can detect all types of fires, but it could be most useful to record small fires ̵
The ECOSTRESS has a pixel size of just 130 x 230 feet (40 x 70 meters) and provides a much sharper view. "We can see a bonfire on the beach," Hook said.
The orbit of ECOSTRESS is also an advantage to find fires. Sun-synchronous satellites fly over the equator in the morning – and thus over most of the earth's vegetation – but agricultural fires are often lit only then or later, and usually die out in the same night. Even the highest resolution sensor in the sun synchronous orbit is likely to be in the right place at the wrong time to see these burns. In addition, most high-resolution satellite sensors show the same location only once every few weeks. From the point of view of the International Space Station, ECOSTRESS is the same location every few days.
If you have watched the coverage of the recent Kilauea outbreak in Hawaii, you may have noticed images from NASA's Advanced Spaceborne Thermal Emission and reflection radiometer. ASTER is one of the most versatile satellite imagery for volcanic eruptions because it can observe both heat and sulfur dioxide flags that can indicate a looming eruption. The ECOSTRESS infrared thermal imaging cameras offer the same observation capabilities and the advantage of faster revision time. If he passes a volcano every few days, he will discover new cracks and hotspots many days earlier than the older ASTER.
The heat of a big city can aggravate the health risks of heat waves, especially for the oldest and youngest city dwellers. Which quarters suffer the most from heat? Which weakenings work best? "With the highly detailed images of ECOSTRESS, the currently ultra-high-resolution thermal infrared space instrument, we will be able to see which climate change measures will keep the neighborhood cool," Hook said. This data could help a city assess the relative effectiveness of mitigation techniques
Coastal and Inland Waters
On coasts and in large lakes, wind can displace surface water to the point where cold water can rise from the depths to the surface , Bring along nutrients. These upgrades of cold water are important food sources for coastal and marine plants and animals. However, researchers wishing to explore satellite data enhancements are hampered by the same two drawbacks that limit their ability to detect small fires: Either the spatial resolution is too coarse to detect the events, or the repetitions are too rare to Capturing incidents only takes a few days (or both). Recognizing these minor enhancements, ECOSTRESS provides valuable information to help understand how the colder, nutrient-rich material moves and dissipates.
As a scout instrument, ECOSTRESS has a limited one-year major mission on the space station. However, the applications described here and their primary purpose of investigating vegetation health have been identified as priorities for space-based observations in both the recent and the current Earth Science Decadal Survey of the National Academy of Sciences. ECOSTRESS measurements help to plan for future observations identified in these surveys.
