“…Duarte et al (2006) and Kruk et al (2010) demonstrated that Jacobs (1978) and Maykut and Church (1973) models showed best performance at two eastern field sites in Brazil. Bilbao and De Miguel (2007) Crawford and Duchon (1999)'s cloudiness factor with the Brunt (1932) model was recommended for all sky conditions in these eleven sites in Florida, US.…”

“…In the end, Brutsaert's formula was used, since it is a formula that, in comparison with the other ones examined, has performed well in several studies under varied climatic conditions (e.g. JIMÉNEZ et al 1987;CULF and GASH 1993;DUARTE et al 2006;BILBAO and DE MIGUEL 2006;KRUK et al 2009). …”

An attempt is made to couple the one dimensional COBEL-ISBA (Code de Brouillard à l'É chelle Locale-Interactions Soil Biosphere Atmosphere) model with the WRF (Weather Research and Forecasting)-ARW (Advanced Research WRF) numerical weather prediction model to study a fog event that formed on 20 January 2008 over Thessaloniki Airport, Greece. It is the first time that the coupling of COBEL and WRF models is achieved and applied to a fog event over an airport. At first, the performance of the integrated WRF-COBEL system is investigated, by validating it against the available surface observations. The temperature and humidity vertical profiles were used for initializing the model. The performance of WRF-COBEL is considered successful, since it realistically simulated the fog onset and dissipation better than the WRF alone. The COBEL's sensitivity to initial conditions such as temperature and specific humidity perturbations was also tested. It is found that a small increase of temperature (*1°C) counteracts fog development and results in less fog density. On the other hand, a small decrease of temperature results in much denser fog formation. It is concluded that the integrated model approach for aviation applications can be useful to study fog impact on local traffic and aviation.

“…Numerous methods have been developed for the daily net radiation parameterization [36][37][38][39][40][41][42], and the methods generally differ in the complexity of their calibration structure and in their use of climatic parameters, variables, and coefficients. The developed and tested robust set of equations proposed by ASCE Environmental and Water Resources Institute (ASCE-EWRI) is suggested as the standardized procedures to calculate daily net radiation [43].…”

Evapotranspiration (ET) plays a key role in water resource management. It is important to understand the ET spatio-temporal pattern of South Asia for understanding and anticipating serious water resource shortages. In this study, daily ET in 2008 was estimated over South Asia by using MODerate Resolution Imaging Spectroradiometer (MODIS) products combined with field observations and Global Land Data Assimilation System (GLDAS) product through Surface Energy Balance System (SEBS) model. Monthly ET data were calculated based on daily ET and evaluated by the GLDAS ET data. Good agreements were found between two datasets for winter months (October to February) with R 2 from 0.5 to 0.7. Spatio-temporal analysis of ET was conducted. Ten specific sites with different land cover types at typical climate regions were selected to analyze the ET temporal change pattern, and the result indicated that the semi-arid or arid areas in the northwest had the lowest average daily ET (around 0.3 mm) with a big fluctuation in the monsoon season, while the sites in the Indo-Gangetic Plain and in southern India has bigger daily ET (more than 3 mm) due to a large water supplement. It is suggested that the monsoon climate has a large impact on ET spatio-temporal variation in the whole region. OPEN ACCESSRemote Sens. 2015, 7 4727
