The 89 and 150 GHz channels operated in window are sensitive to precipitation and humidity. The 183 GHz humidity-sensitive channels and 118 GHz temperature-sensitive channels of the Microwave Humidity and Temperature Sounder (MWHTS) on the Chinese Feng Yun 3C MWHTS (FY-3C MWHTS) polar-orbit meteorological satellite responds in part to precipitation. Combining 118 and 183 GHz channels, the paper...

dry and wet atmospheric depositions as well as urban surface soil samples were collected in eight different land use zones (during 2010) of the most important and largest industrial city, southwest iran for determining cadmium, chromium, lead and zinc. the average of cd, cr, pb and zn concentrations in the study area for wet precipitation were 17.8 μg/l, 49.97 μg/l, 2.31 μg/l, and 0.53 μg/l, re...

the effects of climate change, especially due to the increase of greenhouse gasses, have caused lots of problems that have affected different sections of society. one of the most important effects is the increase of natural disasters such as flood, drought, tropical cyclones, raising sea level, dust storm, etc. drought and flood are the most prevalent of these disasters in iran. because of the ...

A pilot Study was conducted from August 1999 through August 2000 to estimate the loading of selected pollutants from the atmosphere to the San Francisco Estuary. Particulate in the ambient air and precipitation samples were collected at three locations. Dry deposition flux of copper, nickel, cadmium, and chromium was approximately 1100?73, 600?35, 22?15, and 1300?90 μg/m/year, respectively. The...

Stream¯ow simulations for 23 major river basins from the third-generation general circulation model (GCM) of the Canadian Centre for Climate Modelling and Analysis are assessed. Precipitation and runo€ data are used from the AMIP II simulation in which the GCM is integrated for a 17-yr period with speci®c sea surface temperatures and sea-ice concentrations. Compared to the observations, the com...

Over the past decades, rising air temperature has been accompanied by changes in precipitation. Despite relatively robust literature on the temperature sensitivity of carbon cycle at continental to global scales, less is known about the way this sensitivity is affected by precipitation. In this study we investigate how precipitation mediates the response of the carbon cycle to warming over the ...

This study uses a statistical downscaling method based on self-organizing maps (SOMs) to produce highresolution, downscaled precipitation estimates over the state of Pennsylvania in the mid-Atlantic region of the United States. The SOMs approach derives a transfer function between large-scale mean atmospheric states and local meteorological variables (daily point precipitation values) of intere...

[1] In this paper, a simple technique is described for application of radar to retrievals of vertical profiles of precipitation in the Arctic. The method is applied specifically to data from the DOE Atmospheric Radiation Measurement (ARM) North Slope of Alaska– Adjacent Arctic Ocean (NSA-AAO) site near Barrow, Alaska. Profiles of precipitation characteristic size are obtained by developing a re...

Over the last decade, mountain areas have been receiving more concern about organic pollution due to atmospheric transport and deposition processes. Similar to the polar regions these areas are considered some of the most pristine and remote ecosystems worldwide. However, mountains and associated highlands are subject to the atmospheric deposition of Persistent Toxic Substances (PTS) that inclu...
