All about satellites

Meteosat

There are two generations of active Meteosat satellites, Meteosat First Generation (MFG) and Meteosat Second

Generation (MSG), providing images of the full Earth disc, and data for weather forecasts.

Today, weather satellites scan the whole Earth, meaning not a single tropical storm or severe weather system goes undetected. The early detection and warnings they provide have saved thousands of lives.

Meteosat data is of unique value to nowcasting of high impact weather in support of safety of life and property.

It has been shown to improve weather forecasts and severe weather warnings which, in turn helps limit damage to property and benefits industry e.g. transport, agriculture and energy.

L'immagine qui a fianco proviene dalla telecamera che monitora i sensori di temperatura del KWOS inseriti in schermi solari di varia tipologia, dai passivi a quelli a ventilazione forzata.

Gli schermi solari ci vengono forniti dalle aziende che desiderano testarli monitorando da remoto, via web, le loro performances.

Grazie al nostro cruscotto dedicato al Confronto sensori è possibile mettere in relazione alla temperatura, la radiazione solare ed il vento. E' possibile generare "on the fly" grafici contour, a istrogramma o a linea con più variabili.

Per consentire un miglior confronto, sono presenti anche i valori registrati dai sensori di radiazione solare e degli anemometri posti a varie altezze.

E' possibile inoltre, scegliere diversi orari della giornata e periodi dell'anno.

Sulla stessa pagina sono rappresentati i dati di più pluviometri, quelli del disdrometro e del rilevatore di nuvolosità del centro KWOS.

I sensori di temperatura sono calibrati ogni sei mesi in cicli termici in camera climatica. Le misure visualizzate tengono conto degli scostamenti registrati durante la calibrazione.

Microsferics project for lightnings tracking

KWOS is participating to the Microsferics project! Look the result on the Real Time Weather page.

Microsferics Lightning Detection Network, MicroLDN, is a low cost, high accuracy experimental lightning detection network currently operating in parts of Europe and North America.

By using off-the-shelf electronic components and custom designed signal amplifier electronics we created a GPS disciplined time-stamping device for the Boltek range of lightning detectors, making them capable of networked lightning locating using the signal Arrival Time Difference locating method.

Wind speed and direction

ASOS Ice Free Wind Sensor

A majority of older automated airport weather stations are equipped with a mechanical wind vane and cup system to measure wind speed and direction. This system is simple in design: the wind spins three horizontally turned cups around the base of the wind vane, providing an estimation of the wind's speed, while the vane on top turns so that the face of the vane offers the least resistance to the wind, causing it to point in the direction the wind is coming from and thus providing the wind direction.

The new generation of sensors use sound waves to measure wind speed and direction. The measurement is based on the time it takes for an ultrasonic pulse to travel from one transducer to another, which varies depending on - among other factors - the wind speed. The transit time is measured in both directions for several (usually two or three) pairs of the transducer heads. Based on those results, the sensor computes wind speed and direction. Compared to mechanical sensors, the ultrasonic sensors offer several advantages such as no moving parts, advanced self-diagnostic capabilities and reduced maintenance requirements.
