Although many SST products are available, great challenges are still faced when attempting to directly explore the evolution...
The term “temperature anomaly” means a departure from a reference value or long-term average. A positive anomaly indicates that the observed temperature was warmer than the reference value, while a negative anomaly indicates that the observed temperature was cooler than the reference value. The re...
As greenhouse gas concentrations rise, so does global mean surface temperature (GMST). GMST is measured using a combination of air temperature two meters over land, and sea surface temperature in ocean areas from various databases, typically expressed as an anomaly from a baseline period. ...
Regional uplift of these undeformed marine deposits can be achieved by a combination of emplacement of an asthenospheric temperature anomaly and lithospheric mantle thinning60,61. Dynamic topography undoubtedly makes a profound contribution to relative sea-level changes, ancient oceanic circulation, ...
The omnipresence of ocean eddies became apparent from early satellite data of ocean color and sea surface temperature in the late 1970s36,37, and those variables have been used for eddy identification since then38–40. The advent of sea level anomaly observations from satellite radar altimeters ...
also challenging. This paper proposes a support vector machine (SVM) method to estimate subsurface temperature anomaly (STA) in the Indian Ocean froma suite of satellite remote sensing measurements including sea surface temperature anomaly (SSTA), sea surface height anomaly (SSHA), and sea surface ...

The average land surface albedo and its anomaly are shown in Figure 5. The average albedo over land surface is about 0.2 not including the Antarctic region. There are significant seasonal variations. Although there is no single identifiable overall trend, we can clearly identify a decreasing trend...
September 2023 was the warmest September globally, with the highest temperature anomaly of any month in any year since 1940 in the ERA5 dataset1. September 2023 also broke the previous monthly record by an exceptionally large margin: the previous record, set in 2020, was broken by 0.5 °...
anomaly of mean sea level pressure (MSLP). Thus, initially 24 regions of maximum occurrence of LARs were identified, but only those regions that showed an associated negative wintertime MSLP anomaly (Supplementary Figs.1–3), were considered for moisture uptake analysis. A total of four regions ...
