For all energy site records, the entire horizontal land coverages per facility (m2) were measured (using satellite maps) and then divided by the energy output (kWh/a).
We found that increased greenness within 100 m of residences measured using satellite-derived NDVI was associated with higher term birth weight and with reduced likelihood of very (< 30 weeks) and moderately (30 36 weeks) preterm births and SGA.
Nose (2016) studies the long-term variations in the plasma sheet ion composition and sub-storm occurrence over 23 years using the energetic ion flux (9.4 212 keV/e) data measured using Geotail satellite and sub-storm occurrences evaluated from the number of Pi2 pulsations detected at the Kakioka observatory.
Tree and shrub cover was measured using multi-spectral satellite imagery classified with a normalized differences vegetation index (NDVI).
Based on the parallax of 768.7 ± 0.3 milliarcseconds, measured using the Hipparcos astrometry satellite, and more precisely with the Fine Guidance Sensors on the Hubble Space Telescope, Proxima Centauri is about 4.24 light years from the Sun, or 270,000 times more distant than the Earth is from the Sun.
School location was measured using a global positioning satellite receiver (eTREX; Garmin International, Olathe, KS).
Within these buffer zones the area of old forests was measured using kNN (k- Nearest Neighbour) satellite mapping, with a 25×25 m resolution.
Earth's overall reflectivity, or albedo, depends almost entirely on cloud cover and is difficult to measure with any certainty using satellites, said Dr. Loren Acton, a solar physicist at Montana State University who was not involved in the research.
Yes, we can measure methane over large areas using satellites.
The findings also suggest that previous techniques using satellites to measure drought stress in rainforests may be missing dire impacts of a warming global climate, which many scientists believe will cause more droughts in those critical habitats.
