The third flight of the Medium Scale Anisotropy Measurement (MSAM1), in June 1995, observed a new strip of sky, doubling the sky coverage of the original MSAM1 dataset. MSAM1 observes with a 0. 5 beam size in four bands from 5–20 cm. From these four bands we derive measurements of cosmic microwave background radiation (CMBR) anisotropy and interstellar dust emission. Our measurement of dust emi...
Climate change would significantly affect the temporal pattern and amount of annual precipitation at the regional level, which in turn would affect the regional water resources and future water availability. The Peace Region is a critical region for northern British Columbia’s social, environmental, and economic development, due to its potential in various land use activities. This study invest...
Simulation of climate change in Iran during 2071-2100 using PRECIS regional climate modelling system
Parameters such as future precipitation, temperature, snowfall, and runoff were modeled using PRECIS regionalclimate modeling system in Iran with the horizontal resolutions of 0.44×0.44°C in latitude and longitude under SRESA2 and B2 scenarios. The dataset was based on HadAM3p during the periods of 1961-1990 and 2071-2100. Theoverall precipitation error of the model in the period of 1961-1990 w...
The study aimed to find out possible changes in climatic data (temperature and rainfall) from the regional climate model viz. PRECIS(Providing Regional Climates for Impact Studies)under different SRES scenarios (A1B, A2 B2 scenario) by mid (2021-2050) end (2071-2100) century at six locations of Punjab representing agroclimatic zones their impact on maize yield using crop growth simulation model...
Abstract A scenario for future storm surge heights for the tide gauge of Hamburg St. Pauli is constructed on the basis of results from a regional model for Cuxhaven. Under the A2 emission scenario, an increase of the mean annual maximum water level of about 0.1724 m appears possible and plausible for the time horizon of 2030. In Cuxhaven, an increase of 0.14 may be expected in this scenario. In...
Predicting long-term consequences of climate change on hydrologic processes has been limited due to the needs to accommodate the uncertainties in hydrological measurements for calibration, and to account for the uncertainties in the models that would ingest those calibrations and uncertainties in climate predictions as basis for hydrological predictions. We implemented a hierarchical Bayesian (...
The effects of potassium fertilizer (K2SO4) levels K0, (0), K1,(150) and K2,(250 kg/ha) in two species of Brassica napus (Hyola 401 Hybrid) and Brassica juncea (landrace cultivar), under three irrigation regimes, control (irrigation after 50%,), moderate stress, (irrigation after 70%), and severe stress (irrigation after 90% soil water depletion) were studied in a factorial experiment laid out ...
In this paper, we examine the changes in ambient ozone concentrations simulated by the Community Multiscale Air Quality (CMAQ) model for summer 2002 under three different nitrogen oxides (NOx) emission scenarios. Two emission scenarios represent best estimates of 2002 and 2004 emissions; they allow assessment of the impact of the NOx emissions reductions imposed on the utility sector by the NOx...
predicting the impacts of climate change on irrigated wheat yield in fars province using apsim model
background and objectives: over the last decade, climate change has been one of the most challenging issues in the scientific papers. studying the impacts of climate change on crop productivity at regional scale will depend on the right estimate of future climate. this estimation is being implemented by climate models and most of them by general circulation models (gcms). this study aims at pre...
population growth can greatly impact on greenhouse gas emission pattern in the future. considering the importance of population growth in climate change studies, the present research concentrates on the population growth of the middle east in the late 21th century based on the iiasa population scenarios. under the projections of a1-b1 scenario, the world’s population will grow up to 8.7 billion...
