Wildfires In Brazil
The 2020 Brazil rainforest wildfires were a series of forest fires that were affecting Brazil, with 44,013 outbreaks of fires registered between January and August in the Amazonas (Brazilian state), Amazonas and Pantanal. Within the Amazon, 6,315 outbreaks of fire were detected in the same period. Within the Pantanal, the volume of fires is equivalent to those of the past six years and there have been actions by NGOs and volunteers to save endangered animals, such as the jaguar. It was expected that the health systems of the Amazon region, already overloaded by the COVID-19 pandemic, would be even more overloaded due to respiratory diseases due to smoke emitted by the wildfires. Expertise carried out points out that the fires in the Pantanal were started by human action and the Environmental Police Station investigates who are possibly responsible. Douglas Morton, head of NASA's Biospheric Sciences Laboratory, considers fires to be "unprecedented". Although the Brazilian governme ...

MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Earth orbit: one on board the Terra (EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (EOS PM) satellite, launched in 2002. Since 2011, MODIS operations have been supplemented by VIIRS sensors, such as the one aboard Suomi NPP. The systems often conduct similar operations due to their similar designs and orbits (with VIIRS data systems deisgned to be compatible with MODIS), though they have subtle differences contributing to similar but not identical uses. The MODIS instruments were built by Santa Barbara Remote Sensing. They capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions (2 bands at 250 m, 5 bands at 500 m and 29 bands at 1 km). Together the instruments image the entire Earth every 1 to 2 days. They are designed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
