Ein Suchaufruf unseres britischen Partnervereins COL zur partiellen Sonnenfinsternis am 20. März 2015:

Partial solar eclipse – Friday 20 March – your observations wanted!

You are invited to contribute observations of surface air temperature, relative humidity, wind speed and direction, as well as (if available) any cloud-cover and cloud-type observations for the forthcoming deep partial solar eclipse on Friday 20 March. Observations are welcomed for the whole day (00-24 hours), and preferably for 3 days before and after the event, if available, to provide several ‘control’ days.

Any observations will be gratefully received and acknowledged, especially automatic-weather-station data of the requested parameters, recording in GMT (UTC), at a time interval of no greater than 10 min (1-5 min frequency would be ideal). Please check your AWS/system clock beforehand and ensure time synchronisation from an accurate source to within 1 minute.

Please email observations, which should be in .dat, .txt, .csv or Excel file format, as soon as possible after the event (preferably by 3 April) to ehanna@sheffield.ac.uk with ‘Eclipse met obs: [STATION NAME]’ in the email subject header. Most AWS software can export data in one of these formats – look for ‘export file’ or similar in your AWS software menu.
