A study revealed that the temperature of the Earth dropped during last year’s eclipse of the sun, Britain’s Met office has said.
The Met Office on Monday said it was the first time that satellites had
been used to monitor surface “skin” temperatures during a total solar
eclipse, Xinhua news agency reported.
The research showed the eclipse on March 20 last year resulted in a drop
in land surface temperatures in parts of Britain and Europe.
The satellite results were combined with a study of one-minute
observations of near-surface air temperature from meteorological
stations across Britain, allowing scientists to build a picture of the
factors that influence how the temperature changes during a solar
eclipse.
“The results show that the amount of sun obscured by the moon, the
eclipse duration and the timing, all influence the temperature drop
during the event,” a Met official said.
“The largest temperature drops occurred where the sun was most obscured,
the eclipse was longer, or the timing was earlier in the day,” he said.
Two scientific papers, written by Met office scientists Elizabeth Good
and Matt Clark, will be published in a special solar eclipse edition of
the Royal Society’s Philosophical Transactions.
Good, from the Climate Monitoring and Attribution Team, said: “Local
factors, such as vegetation cover, land use and cloud cover has resulted
in previous studies struggling to find links between temperature and
the obscuration of the sun.”
“However, the use of satellite data from across a large area has allowed
for this to be investigated using observed data for the first time.”
The March 2015 eclipse was total across the North Atlantic, the Faroe
Islands and Svalbard, and partial in Europe, Iceland, parts of North
Africa and northern Asia. For most of the Europe, the eclipse was a
morning event.
