The Australian Bureau of Meteorology provides flood forecasting and warning services across Australia for most major rivers in Australia, cooperation with other government, local agencies emergency services. As part this service, the issues a watch product to provide early advice on developing situation that may lead flooding up 4 days prior an event. This service is based (a) ensemble available Numerical Weather Prediction (NWP) rainfall forecasts, (b) antecedent soil moisture, stream dam...

The emerald ash borer (EAB) poses a significant economic and environmental threat to trees in southern Ontario, Canada, the northern states of USA. It is critical that effective technologies are urgently developed detect, monitor, control spread EAB. This paper presents methodology using multisourced data predict potential infestations EAB town Oakville, Canada. information combined this study includes remotely sensed data, such as high spatial resolution aerial imagery, commercial ground...

We evaluate the use of reference modules for monitoring effective irradiance in PV power plants, as compared with traditional plane-of-array (POA) sensors, and capacity tests. Common POA sensors such pyranometers cells are unable to capture module-level nonuniformity require several correction factors accurately represent conditions fielded modules. These problems compounded bifacial systems, where loss due rear side shading rear-side (RPOA) gradients greater more difficult quantify. The...

Abstract Accurate solar radiation measured by radiometers depends on instrument performance specifications, installation method, calibration procedure, measurement conditions, maintenance practices, location, and environmental conditions. This study addresses the effect of different methodologies resulting differences provided radiometric service providers such as National Renewable Energy Laboratory (NREL) manufacturers radiometers. Some these methods calibrate indoors some outdoors. To...

Canopy vertical parameters, such as tree height, side shape and gap fraction are critical for forestry studies. However, it is not trivial to retrieve them from remotely sensed data. Currently, only LiDAR data can directly provide some of these parameters. Due low availability relatively high cost, still crucial develop methodologies that derive parameters other In this study, a longitudinal profile based approach introduced on unmanned aerial vehicle (UAV) imagery, which has successfully...

Banks financing solar energy projects require assurance that these systems will produce the predicted. Furthermore, utility planners and grid system operators need to understand impact of variable resource on conversion performance. Accurate radiation data sets reduce expense associated with mitigating performance risk assist in understanding impacts variability. The accuracy measured by radiometers depends instrument specification, installation method, calibration procedure, measurement...

In recent years, bifacial modules have been attracting industry interest due to the potential for significant contributions energy generation from module rear side. Albedo is a critical parameter needed modeling side irradiation, and accurate albedo values representing both longterm evolving conditions are quantify impact of additional financing solar projects. this paper, authors identify multiple sources long-term data compare shorter term ground-based measurements in Utah California. An...

Soil productive is critical to Earth surface vegetation management and monitoring with significant environmental economic value. The human impact has played a very important role in agriculture forest soil disturbances. In this study, high spatial resolution multi-spectral imagery was investigated for its value potential treatment study. Individual tree height DBH were retrieved from the used estimate biomass, which expected be indicator of ground treatment. Controlled experimental sites...

the convolution of spectral response with solar irradiance are considered. The second is most accurate technique.

Douglas-fir (Pseudotsuga menziesii) is a highly valued lumber for heavy duty construction which exceptionally hard, stiff and durable. However, it has long growth circle very sensitive to the environmental changes, particularly ground treatments. In this study, we try use remote sensing technique assess Douglas fir productivity under different We developed two stages approach. species classification stage, applied an innovative crown pattern recognition approach on high spatial resolution...
