July 2009 experienced a large jump in the global average tropospheric temperature anomaly, from +0.00 deg. C in June to +0.41 deg. C in July, with the tropics and southern hemisphere showing the greatest warming.

NOTE: For those who are monitoring the daily progress of global-average temperatures here, we will be switching from NOAA-15 to Aqua AMSU in the next few weeks, which will provide more accurate tracking on a daily basis. We will be including both our lower troposphere (LT) and mid-tropospheric (MT) pre-processing of the data.
