Metop-C Satellite Added to Our Processing
With this update, we have added Metop-C to our processing, so along with Metop-B we are back to having two satellites in the processing stream. The Metop-C data record begins in July of 2019. Like Metop-B, Metop-C was designed to use fuel to maintain its orbital altitude and inclination, so (until fuel reserves are depleted) there is no diurnal drift adjustment needed. Metop-B is beginning to show some drift in the last year or so, but it’s too little at this point to worry about any diurnal drift correction.
The Version 6.1 global average lower tropospheric temperature (LT) anomaly for November, 2024 was +0.64 deg. C departure from the 1991-2020 mean, down from the October, 2024 anomaly of +0.75 deg. C.
The Version 6.1 global area-averaged temperature trend (January 1979 through November 2024) remains at +0.15 deg/ C/decade (+0.21 C/decade over land, +0.13 C/decade over oceans).
The following table lists various regional Version 6.1 LT departures from the 30-year (1991-2020) average for the last 23 months (record highs are in red). Note the tropics have cooled by 0.72 deg. C in the last 8 months, consistent with the onset of La Nina conditions.
