Direct and diffuse solar irradiation, and infrared sky flux are considered as incident radiation. The fog occurs from adding water vapor into the air. We also show that meteorological factors were not the main reason for the dramatic reductions of pollutants in the atmosphere. The change vector is simply the vector difference between successive time-trajectories, each represented as a vector in a multidimensional measurement space. Compared to other pollutants, NO2 experienced the most significant reductions by almost 54%, 83%, 33%, and 19% decrease in BTH, Wuhan, Seoul, and Tokyo, respectively. Locations of current fires and the extent of previous fire activity are ascertained using satellite imagery acquired by the MODIS sensor. Radiative heat transfer in the fog layer is analyzed. Since fog is created during the night, AVHRR data is used for fog detection at night and METEOSAT data is used for fog observation and fog dissipation forecast during the day over a specific area of Greece, lowland Thessalia. Never before has a space-borne instrument been able to provide such detailed information, complementing field and modeling efforts to produce a comprehensive picture . The MODIS products, which were accumulated for a long time and optimized by the new MAIAC (Multiangle Implementation of Atmospheric Correction) algorithm, showed the best accuracy (CC=0.836) and were followed by the products from VIIRS and Himawari-8.

Hence, the adjustment will strongly increase the agreement between the satellite and in situ data and between data from different near-polar orbiting OC imagers; moreover, the adjustment will make available data traditionally masked in the standard processing chains, increasing the VGOCS spatial and temporal coverage, fundamental to analyze the coastal optical variability. The University of Montana is the only Forestry School in the country with a member on the EOS . The Enhanced Vegetation Index (EVI) is a key Earth science parameter used to assess vegetation, originally developed and calibrated for the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra and Aqua satellites 130 comparison should not be considered as an ideal evaluation between satellite and surface-detected fog due to some inherent factors involving131 satellite-based fog detection such as orbital 132 gaps in satellite data as well as the presence of overlaying clouds in the mid-high troposphere, 133 affecting the MODIS retrievals of low-lying fog. MODIS 250 m resolution image with the CALIOP sampling represented by the red line Using a collection of satellite images and data, scientists and visualizers stitched together months of observations of Earth's land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic. The in situ validation shows that the minimum MAE obtained by the optimal band combination is approximately 1 K (root mean square error (RMSE) = 1.12 K; coefficient of determination (R²) = 0.902). Due to high temperature and humidity condition, the radiation cooling at night is not so large even in the clear sky. The method presented here has potential applications in research focused on energy balance, ET estimation, and weather prediction for regions with similar physiographic features to those of the Nile basin. measurement The MODIS cloud mask is designed to be clear-sky conservative, . provide a powerful combination of observations. Early Breakup of the Beaufort Sea Ice. Using the combined CloudSat.CALIPSO (CC) data, five main cloud groups are investigated: Ice-only, ice-above-liquid, liquid-only, ice-above-mixed, and mixedonly clouds that have annual mean frequencies of 28.6 %, 20.1 %, 16.0 %, 9.3 %, and 6.7 %, respectively, Understanding the cloud cover characteristics over calibration test sites is very important for vicarious calibration and automated facilities measurement. Comparison between the retrievals from our algorithm and that from Korea Meteorological Administration (KMA) algorithm, shows that the KMA algorithm often misconceived sea fog as stratus, resulting in underestimating the occurrence of sea fog. Changes in continental water storage impact the regional water budget and can, in extreme cases, result in floods and droughts that often claim a high toll on infrastructure, economy and human lives. Combinations of specific satellite bands are used to detect clouds of dust or sand.
