We developed an agrivoltaic greenhouse (a ‘test cell’) that partially trapped waste heat from two photovoltaic (PV) panels. These panels served as parts of the roof enclosure to extend growing season. Relative humidity, internal air temperature, incident solar radiation, wind speed, and direction were measured for one year. A locally 1-D transient moisture transport model, well a shadowing was ...

in this study, by using minimum, maximum and mean daily interpolated data from asfazari data base, the changes of agro climatic indices analyzed in iran during 1962-2004. at first, the indices calculated for each pixels and then trend and slope value evaluated by nonparametric mann-kendal and parametric regression method. in total, the results showed that the indices have positive trend on the ...

[1] The global climate models for the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4) predict very different changes of rainfall over the Amazon under the SRES A1B scenario for global climate change. Five of the eleven models predict an increase of annual rainfall, three models predict a decrease of rainfall, and the other three models predict no significant change...

Fossil-fuel combustion related winter heating has become a major air quality and public health concern in northern China recently. We analyzed the impact of winter heating on aerosol loadings over China using the MODIS-Aqua Collection 6 aerosol product from 2004-2012. Absolute humidity (AH) and planetary boundary layer height (PBL) -adjusted aerosol optical depth (AOD*) was constructed to refle...

The total PAH associated to the airborne particulate matter (PM10) was apportioned by one receptor model based on positive matrix factorization (PMF) in an urban environment (Zaragoza city, Spain) during February 2010-January 2011. Four sources associated with coal combustion, gasoline, vehicular and stationary emissions were identified, allowing a good modelling of the total PAH (R(2) = 0.99)....

Both local and large-scale processes affect the Amazon hydrologic cycle. We investigate the impact of deep soils on the atmosphere through local feedbacks. The Simple Biosphere model, version 3 (SiB3), is coupled to a single column model. Historically, land surface schemes parameterize soil moisture stress based on shallow soils and incorrectly capture seasonal cycles in the Amazon. Following o...

The field experiment was carried out at research farm of Department Agricultural Meteorology, Chaudhary Charan Singh Haryana University, Hisar, during Kharif season 2017-18 to study the influence different growing environments on Clavigralla gibbosa population dynamics and its relationship with microclimate pigeonpea cultivars. results revealed that egg masses adult C. were first recorded 38th ...

the fact that water is the most important factor of life on earth is not a new concept. alteration and reduction in the amount of precipitation, population explosion and contamination of underground water pressurize governments severely to find solution for water resources. the air moisture is one of fresh water resources which has not been noticed and well exploited. in this study proper place...

Wheat crop is attacked by number of diseases some which cause yield losses and deteriorates quality. Rust pathogens are most important wheat can considerable economic if uncontrolled. Stripe rust, caused Puccinia striiformis f. sp. tritici, an disease common in growing areas experiencing cold humid weather conditions during the season. Different meteorological parameters influence occurrence de...
