FP7 - Rsearch for SME - PolCloud - Fully-sky cloud detection by means of imaging polarimetry and polarization measurement of the cloud-base height
| Zusammenfassung | A Hungarian Research Institute is intended to submit a proposal to the FP7 ‘Research for SMEs’ call and invites SME partners to participate in developing a novel cloud detector that delivers more information than conventional instruments, based on the patterns of skylight polarization measured by 180o field-of-view imaging polarimetry. The instrument improves the accuracy and reliability of traditional photometric cloud detection algorithms. SMEs providing meteorological services are awaited. |
| Beschreibung | The need: The market of automatic cloud detectors is very young (approximately one decade old), thus the available instruments are not accurate and fast enough. These problems have to be solved before a reliable cloud detector network can be created, the results of which can be successfully incorporated into the climatic models and can be used for short-term weather forecast purposes. The new instrument developed in the project, being more accurate than the existing cloud detectors, will help to solve these problems. Weather forecast: There exist 4 major climatic models in the world that can be used for weather forecast. These models use current and past weather data to predict the probable weather conditions in the more or less near future. One of these weather data is the cloud coverage that can be seen from a given geographical point on the Earth’s surface. The percentage and type of cloud coverage are usually estimated by human observers, introducing several problems (e.g., inaccuracy, unreliability, low spatial resolution, small temporal measurement frequency, high costs) that make it difficult to use these subjective data in climatic models. Nowadays these human observers are starting to be substituted by automatic cloud detectors. Ultra short-term weather forecast: This is a special area of weather forecast, in which very accurate and reliable short-term (0-4 hours) predictions are needed for a limited geographical area. In these applications the real-time detection of the spatiotemporal change of the cloud coverage is essential. This task can be performed by automatic cloud detectors. • Hail forecast for the benefit of agricultural producers The device developed in the project will enhance the forcasting capabilities of hail-suppression services by allowing 1) more precise; 2) better localised and 3) more cost effective hail forecast. • Solar forecast for energy utilities Technologies are being developed to pre-emptively alert energy providers of meteorological changes, allowing them to switch to alternate forms of energy during times of low output from solar energy sources. The device developed in the project, delivering fast, ultra-short-time cloud coverage forecast for a limited geographical area, has the potential to be a vital component of such technologies. The institute is looking for SME partners providing meteorological services in the following area: - Hail-forecasting - Solar forecasting - Ultra-short term local weather forecast Apart from general short-term weather forecast, potential fields of application include solar forecasting and hail forecasting. The improvement in accuracy will stem from the use of full-sky imaging polarimetry. By using 4 times more information (degrees of linear and circular polarization, direction of polarization and intensity in the red, green and blue spectral ranges) of skylight in a given celestial direction (relative to the traditional method using only the intensity of skylight in the red, green and blue parts of the spectrum), more accurate algorithms can be developed to detect clouds. These algorithms will be developed and adapted to fulfil the requirements of the general weather forecasting models, as well as the models used in the specific fields of forecasts targeted in the project. Technical Specifications / Specific technical requirements of the request The project representative, a Hungarian Research Institute, is looking for SME partners, with experience and expertise in meteorological services, especially hail-forecast and solar (irradiation) forecast. Companies with a good EU market presence and broad distribution networks are required to provide maximum exploitation potential.
