BGT: uno schermo solare per il WH31 della Ecowitt

WH31 BGT 01 WH31 BGT 03

Se non si avesse la possibilità o non si volesse modificare il trasmettitore WH31 della Ecowitt

e non si volesse comunque rinunciare ad un buono schermo contro la radiazione solare, consigliamo l'utilizzo di un BGT solar shield la cui versione a 14 piatti, come si può vedere dalle immagini, crea la giusta ventilazione.

 Il KWOS lo ha testato per svariato tempo e confrontato con vari schermi solari sia a ventilazione aspirata attiva, sia passivi.

Le dimensioni sono generose: diametro interno: 61mm, altezza interna:170mm, diametro esterno: 140mm

Viene fornita la staffa per fissaggio a palo sia verticale che orizzontale. Ottima l'idea di distanziarlo dalla staffa con tre grandi distanziatori.

All about lightning

Scarica (solo in italiano):
Studio sull'LPLWS NASA

The phenomenon of lightning is actively investigated since 1752, when the American statesman and scientist B.Franklin one of the first established the electrical nature of lightning. As a whole the picture of formation of lightning is as follows. The terrestrial atmosphere is very good dielectric located between two conductors - a surface of the ground from below and the top layers of an atmosphere, including an ionosphere, from above. These layers are passive components of a global electric circuit. Between negatively charged surface of the ground and positively charged top atmosphere the constant potential difference of about 300.000 V is supported. According to the idea for the first time stated by Wilson in 20th years this ionosphere potential arises from thunder-storms which create global electric "battery". Lightning is a visible electric charge coming from a cloud, going to either another cloud or the earth.  Usually, thunder like the sound you are hearing accompanies lightning, especially during a thunderstorm.

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.
