QUES: High, cold ice clouds such as Cirrus or Cumulonimbus show up bright white, lower warmer clouds such as Stratus or Stratocumulus show up as grey with intermediate clouds shaded accordingly. Hot land surfaces will show up as dark-grey or black. One disadvantage of infrared imagery is that low cloud such as stratus or fog can be a similar temperature to the surrounding land or sea surface and does not show up. However, using the difference in brightness of the IR4 channel (10.3–11.5 µm) and the near-infrared channel (1.58–1.64 µm), low cloud can be distinguished, producing a fog satellite picture. The main advantage of infrared is that images can be produced at night, allowing a continuous sequence of weather to be studied.

QUES: Pope Julius had died in April, 352, and was succeeded by Liberius. For two years Liberius had been favourable to the cause of Athanasius; but driven at last into exile, he was induced to sign an ambiguous formula, from which the great Nicene text, the "homoousion", had been studiously omitted. In 355 a council was held at Milan, where in spite of the vigorous opposition of a handful of loyal prelates among the Western bishops, a fourth condemnation of Athanasius was announced to the world. With his friends scattered, the saintly Hosius in exile, and Pope Liberius denounced as acquiescing in Arian formularies, Athanasius could hardly hope to escape. On the night of 8 February, 356, while engaged in services in the Church of St. Thomas, a band of armed men burst in to secure his arrest. It was the beginning of his third exile.

QUES: The trip was intended to soften the strong isolationist tendencies among the North American public with regard to the developing tensions in Europe. Although the aim of the tour was mainly political, to shore up Atlantic support for the United Kingdom in any future war, the King and Queen were enthusiastically received by the public. The fear that George would be compared unfavourably to his predecessor, Edward VIII, was dispelled. They visited the 1939 New York World's Fair and stayed with President Franklin D. Roosevelt at the White House and at his private estate at Hyde Park, New York. A strong bond of friendship was forged between the King and Queen and the President during the tour, which had major significance in the relations between the United States and the United Kingdom through the ensuing war years.
In what city is the White House?
