Climate Diagnostics Bulletin Updates to Climatologies and Indices Beginning with January 2011 Data (To be released in February 2011)Beginning with the
January 2011 monthly data, all climatologies, anomalies, and indices
presented within and related to the monthly Climate Diagnostics Bulletin
will be updated according to current WMO standards. For datasets that
span at least the past 30 years (such as atmospheric winds and
pressure), the new anomalies will be based on the most recent 30-year
climatology period 1981-2010. For data records shorter than 30 years
(such as sub-surface temperature anomalies), the new anomalies will be
based on climatologies that begin with the earliest date possible and
extend through 2010. Another such climatology update will only occur ten
years from now, in 2021. |
