The Weather Research and Forecasting (WRF) model coupled with an Urban Canopy Model (UCM) was used for studying urban environmental issues. Because land use data employed in the WRF model do not agree with the current situation around Guangzhou, China, the performance of WRF/UCM with new land-use data extracted from Remote Sensing (RS) data was evaluated in early August 2012. Results from simul...

Despite parallelisation, scalable performance of WRF is often not achieved. Although the WRFV3 Parallel Benchmark Page provides valuable scaling information, this one-domain configuration is often not typical of the general application of WRF to nested domains of varying sizes and shapes. This study is a first step in providing a centralised WRF performance repository for a variety of typical c...

A 1-D canopy interface model (CIM) has been developed recently and integrated in the meso-scale meteorological WRF v3.5 model in order to improve the surface representation. One of the objectives of such a model is to prepare for the coupling of micro-scale models with meso-scale models so as to improve building energy consumption estimates at the urban scale as well as improve meteorological v...

ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...

In this paper, differential maps of total zenith delay (TZD) estimated by GPS and by Weather Research and Forecasting Model (WRF) numerical data are compared with the TZD by Synthetic Aperture Radar (SAR) Interferometry. This maps are generated by processing a set of interferometric SAR images acquired by the ENVISATASAR mission over the Lisbon region from April to November of 2009. To obtain T...

Wedge Range Filter (WRF) proton spectrometers are routinely used on OMEGA and the NIF for diagnosing ρR and ρR asymmetries in direct- and indirect-drive implosions of D(3)He-, D2-, and DT-gas-filled capsules. By measuring the optical opacity distribution in CR-39 due to proton tracks in high-yield applications, as opposed to counting individual tracks, WRF dynamic range can be extended by 10(2)...

The Weather Research and Forecast (WRF) project is a multi-year/multi-institution collaboration to develop a next generation regional forecast model and data assimilation system for operational numerical weather prediction (NWP) and atmospheric research. Under this project – a collaboration between The National Center for Atmospheric Research (NCAR), Microsoft Corporation, Advanced Micro Device...
