Climate Indices are updated on the 15th of each month.
Temporal variation and current status of climate variability can be effectively monitored in terms of indices. In this section, monthly data of climate indices representing major climate variability with significant implication in the seasonal climate prediction are provided. Indices are categorized into three groups such as Pacific SST, Atlantic SST, Atmosphere, and Monsoon. Time series of each index will be shown by clicking mouse pointer over the name of each index and the data(ascii format) can be downloaded by clicking image. Each data is updated around 10th of each month. You can find more information on the indices at this link.
