Citizen Weather Observer Program  /  NASA-News



Das Citizen Weather Observer Program (CWOP) ermöglicht es Betreibern von automatischen Wetterstationen, ihre Messwerte über Funk oder das Internet an das US-amerikanische Mesonet zu übertragen. Diese Daten werden in weitere Folge aufbereitet und sowohl von der National Oceanic and Atmospheric Administration (NOAA) genützt und stehen ebenso für jedermann frei zugänglich über das Internet zur Verfügung.

 

Diese Anwendung ist sowohl für Funkamateure mit dem eigenen Rufzeichen als auch für Nichtlizensierte nach erfolgreicher Registrierung mit zugeteilter Kennung möglich.

 

Die Registrierung zur Erlangung der erforderlichen individuellen Kennung erfolgt über die

Citizen Weather Program Registration.

 

Das Format für die im APRSWXNET übertragenen Daten beruht auf der APRS-Spezifikation, wobei die Werte in direkt lesbarer Form, jedoch im angloamerikanischen Maßsystem vorliegen.

 

------------------------------------------------------------------------------------------------------------------------------------------------------------

 

Daten, welche über dieses System übertragen werden, enthalten Datensätze, welche an nachstehendem Beispiel  erklärt werden:

Für die Datenerfassung  von der eigenen Wetterstation am PC mit implementierten Möglichkeiten, diese Wetterdaten sowohl in das APRS-Netz als auch an weitere oder andere Plattformen nahezu in Echtzeit zu übertragen, eignet sich die kostenfreie Software CUMULUS besonders gut.

 

Zudem werden bei CUMULUS zahlreiche verschiedene Typen von Wetterstationen unterstützt. Die Verbindung einer Wetterstation zum PC erfolgt über eine serielle oder USB-Schnittstelle.

Speziell für die Übertragung in das APRS-Netz sowie zu der Wetterplattform Weatherunderground sind auch Ethernet-Interfaces verfügbar, welche die Wetterdatenübertragung ohne PC durchführen.

 

Erforderlich ist meist ein LAN-Anschluss sowie eine RS-232-Verbindung (serielle Schnittstelle) zur Wetterstation (z.B. Peet Bros Ultimeter, WS 2300, WS 2307, WS 2350).

 

Ein Beispiel für ein solches Interface ist das WXEth 2.0 von Microsat:
