Complete cloud-free satellite shots of Ireland are extremely rare. According to NASA’s Image of the day site:
Ireland receives between 750 and 2000 millimeters (29 and 78 inches) of rain per year, with more rain falling in the west and in the mountains. Most of the rain falls in light showers.
the sky is entirely cloudy more than 50 percent of the time
To celebrate St Patrick’s day NASA has released this gorgeous, once in a lifetime glimpse of the Emerald Isle without any cloud cover. The photo was captured on October 11, 2010 by the Aqua satellite.
