Trends in Total Cloud Amount Over China from CDIAC
Entry ID: CDIAC_TRENDS_CLOUDS

[ Update this Record ]

Summary
Abstract: This data set is a cloud amount time series derived from Kaiser
(1998). The cloud data were extracted from a database of 6-hourly
weather observations provided by the National Climate Center of the
China Meteorological Administration (CMA) to the U.S. Department of
Energy's Carbon Dioxide Information Analysis Center (CDIAC) through a
bilateral research agreement. Surface-observed (visual) six-hourly
observations [0200, 0800, 1400, and 2000 Beijing Time (BT)] of cloud
amount (0-10 tenths of sky cover) were available from 196 Chinese
stations covering the period 1954-94. Data from 1951-1953 were also
available; however, they only included 0800, 1400, and 2000 BT
observations. The data extend over eight Chinese regions: (1) Western
Northwest (WNW), (2) Eastern Northwest (ENW), (3) North, (4) Northeast
(NE), (5) Tibet, (6) Southwest (SW), (7) East, and (8) South.
