The objective of this study is to investigate the potential of nighttime light data, acquired with Defense Meteorological Satellite Program Operational Linescan System (DMSP/OLS) owned by National Oceanic and Atmospheric Administration (NOAA), in predicting urban daily particulate matter (PM)2.5 with an aerodynamic diameter of less than 2.5 μm average concentrations. To achieve the purpose, we ...

extended abstract 1. introduction ascent rainfall mechanism is “one of the most important factors in leading to various rainfall behaviors in different regions, such as various atmospheric precipitation seen in different time scales” (masoompour, miri, zolfaghari, & yarahmadi, 2013, p. 299). in fact, some of them can be called atmospheric phenomena due to their special nature. one of these atmo...

Hail phenomenon is one of the hazardous weather phenomena that can make the highest amount of damage to farms, gardens, cars, rooftops, etc. in a very short time (a few minutes), depending on the diameter of the particles. One of the best ways to study this devastating climatic phenomenon is the use of atmospheric instability indices. The indices which are calculated with the help of radiosonde...

[1] A climate model, coupled to a sophisticated land surface scheme, is used to explore the impact of land use induced land cover change (LULCC) on climate extremes indices recommended by the Expert Team on Climate Change Detection and Indices (ETCCDI). The impact from LULCC is contrasted with the impact of doubling atmospheric carbon dioxide (CO2). Many of the extremes indices related to tempe...

We used a data mining algorithm to evolve fuzzy association rules between the atmospheric indices and the Summer Monsoon Rainfall of All-India and two homogenous regions (Peninsular and West central). El Nino and Southern Oscillation (ENSO) and Equatorial Indian Ocean Oscillation zonal wind index (EQWIN) indices are used as the causative variables. Rules extracted are showing a negative relatio...

the physico-chemical characteristics and physiological qualities of palm (phoenix dactylifera) fruit strongly depend on the storage conditions. storage environment and packaging type are the factors most influencing on the quality of dates during their storage. date fruits were packed within an aerobic atmosphere, vacuumed in pa/pe pouches and stored at different temperatures (-20, 4, 25 and 40...
