This Advanced Synthetic Aperture Radar (ASAR) multitemporal color composite image shows an area covering the city of Dublin, which appears as a large bright area in the bottom part of the image. The image is composed of three ASAR IMP images acquired on different dates and assigning a color (RGB) to each date (Red: 11 October 2003 - Green: 04 January 2003 - Blue: 21 September 2002). Dublin, the capital of Ireland and one of the largest ports on the Irish Sea (in the right part of the image), is called Baile Atha Cliath in Gaelic, which means "Town of the Hurdle Ford". The terrain is generally flat as can be seen in the image, except in the south of Dublin where appear the Wicklow Mountains and in the top right part of the image where the Mourne Mountains are. The River Liffey flows through the city into Dublin Bay, dividing Dublin into north and south sides. The two ends of the Dublin Bay are Howth Point, the circular peninsula near the upper right side of the image, and Dun Laoghaire, the point to the south. Off the coast are the islands of "Ireland's Eye" (the small one just north of Howth) and Lambay Island, the largest island seen in the image. The tidal planes are clearly visible along the coastline principally in bright green color. The colors of the sea merely reflect the wind situation during the data acquisitions. Runways of the Dublin International Airport are clearly seen in the north of the city. The different colors of the fields seen in the image are due to different crop conditions the day the three images were acquired.
