Definitions and mathematical formulas of the indices used in SACA&D are
provided below. A core set of
21 indices follows the definitions recommended by the CCl/CLIVAR/JCOMM Expert
Team on Climate Change Detection and Indices (
ETCCDI
). Another
22 indices are specifically for Southeast Asia. Note that new research may
lead to additional indices or changes in the indices definitions in the
future.
The station series used for indices calculation in SACA&D are
blended
series. This means that they are made near-complete by infilling from
nearby stations and updated using synoptical messages. Details on the
blend and update proces are given in the
specific FAQ
or in Project Info >
ATBD
.
The
43 indices have been grouped in different categories corresponding with
different aspects of climate change. The same grouping is also used in the
pull down menus for presenting indices plots and maps.
