Xiong and A. Wu and B. Wenny and S. Madhavan and Zhipeng Wang and Yonghong Li and N. Chen and W. … MODIS (Moderate Resolution Imaging Spectroradiometer) instrument is presented. Since several years ago, satellites have been used to detect fires. Also, the dust detection scheme based on A-MODIS was successfully transferred to the follow-on sensors such as Suomi (SNPP) and NOAA 20 (N20) VIIRS. Office for Outer Space Affairs MODIS has 20 RSBs (bands 1–19, 26) with wavelengths ranging from 0.4 to 2.3 m and 16 TEBs (bands 20–25, 27–36) covering a spectra range from 3.6 to 14.4 m. The new MODIS Land Surface Temperature and Emissivity (LST&E) product (MOD21) available in Collection 6 uses a physics-based algorithm to dynamically retrieve both the LST and Emissivity simultaneously for the three MODIS thermal infrared bands (29, 31 and 32) at a spatial resolution of 1 km at nadir. The MOD21 product addresses the documented cold bias of 3-5 K in the MOD11 heritage split-window products over arid and semi-arid regions. It has a swath width of 2,330 km and 12-bit radiometric_resolution meaning it can distinguish radiation in 4096 different levels for each band. Found insideThe Arctic Climate System provides a comprehensive and accessible overview of the subject for researchers and advanced students in a wide range of disciplines. These satellites have similar orbits, but the spatial resolution of their sensor’s thermal bands is different. The thermal band of MODIS has a 1,000 meters resolution per pixel whereas VIIRS has a 375 meters resolution per pixel. This higher resolution enables VIIRS to detect fires that MODIS overlooks. Observations from the 16 thermal emissive bands (TEB), covering wavelengths from 3.5 to 14.4 m with a nadir spatial resolution of 1 km are used to regularly generate a variety of atmosphere, ocean and land … Found insideA comprehensive manual exploring radiometry methodologies and principles used with satellite-, radiometer- and thermal-camera data, for academic researchers and graduate students.

MODerate Resolution Imaging Spectroradiometer (MODIS) on the Terra (T) and Aqua (A) platforms have been a versatile sensor for well over 21 and 18 years respectively, and have been extremely useful in the retrieval of aerosol information over the entire globe. Product Description: This Level 1B data set contains calibrated and geolocated radiances at-aperture for MODIS spectral bands 1 through 7 at 500m resolution. Each of the TEB contains 10 detectors which record samples at a spatial resolution of 1 km. MODIS, the cornerstone instrument of Terra, pro-vides daily global coverage in its 36 reflectance and thermal infrared (TIR) spectral bands at 1 km resolution or better (Table 1). A daily complement of 44 science products is created from the MODIS L1B radiances to monitor the geophysical signatures ofglobal climate andclimate change. By analyzing a sufficiently large amount of those most overlapped pixels, the systematic error of each detector in the TIR bands can be estimated. Second, we analyse data from four different times of day (morning, afternoon, evening and predawn) and for three different bands (MODIS bands 20, 32 and a ratio thereof); and third, we use an unbiased automated algorithm for thermal anomaly extraction of local thermal anomalies. MOD14A1 is produced every 8 days at 1-kilometer resolution as a gridded level-3 product in the Sinusoidal projection. The high correlation of the TEBs with the AOT allowed a successful characterization of the TEDI.

Abstract: Moderate Resolution Imaging Spectroradiometer (MODIS), whose openly public data have been used for over two decades to monitor and address global issues, has 16 thermal emissive bands (TEBs) with central wavelengths that range from 3.7 to 14.4 μm and are calibrated on-orbit using observations from its on-board blackbody. Terra was launched by NASA on December 18, 1999, into a sun synchronous, … MODIS is NASA’s flagship sensor system with 36 spectral bands in the visible and infrared (from near to thermal)regionofthespectrum(0.4–14.4Am).Twoof its bands operate at a nominal spatial resolution of 250 m at nadir, with five bands at 500 m and the remaining 29 bands, including the thermal infrared bands of interest, at 1000 m. As A-MODIS continues to perform well beyond its designed lifetime of 6 years, the instrument has undergone various levels of degradation during its mission time. Average daily, weekly (8 day), monthly and annual skin SST products are available at both 4.63 and 9.26 km spatial resolution. The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA’s Terra and Aqua satellites has been used to scan the Earth’s surface for fires on a daily basis for almost 15 years. VIIRS Earth view scenes in the moderate-resolution bands contain 3200 samples in the scan direction within a scan angle range of 56 off nadir and 16 detectors in the track direction. MODIS has 36 spectral bands spanning from the visible to the thermal-infrared (IR) spectrum. Since the MODIS Thermal Emissive Bands (TEB) are well calibrated on-orbit using a BlackBody (BB) source, the calibration of these long wave infrared bands is quite robust.
