Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System

open access: yesReviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Contrail and Cirrus Observations over Europe from 6 Years of NOAA-AVHRR Data [PDF]

open access: yes, 2002
Thin ice clouds – cirrus and contrails – are analysed in a long-term 1 km data set from the Advanced Very High Resolution Radiometer (AVHRR). Here twice daily data received at DLR Oberpfaffenhofen covering most of Europe over the full lifetime of the ...

NOAA/AVHRR画像の自動GCP生成 [PDF]

open access: yes, 2010
application/pdfTime series analysis is one of the important methods for understanding the change of phenomenon. But, the geographical gaps are generally included among satellite image. Therefore, geometric correction of these gaps is needed.

Submesoscale Thermal‐Feedback Coupling Coefficients in Intense Oceanic Boundary Current Systems Revealed by SWOT

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Ocean motions at mesoscales (∼100 km) and below actively trigger air‐sea interactions by inducing anomalies of sea surface temperature (SST) and currents. Despite extensive research on oceanic submesoscale (O (0.1–10) km) processes, observational understanding of submesoscale air‐sea interactions remains limited.

Solar Heating of the Arctic Ocean Driven by Changes to Sea Ice Albedo

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The sea ice albedo feedback is the process by which Arctic warming causes sea ice retreat, which due to the reduction in surface albedo leads to further Arctic warming through increased solar absorption. This definition, however, neglects important associated changes in cloud cover that can mitigate this effect, as well as covariant changes in

Noaa's avhrr archive

open access: yesGeocarto International, 1991
Abstract The Satellite Data Services Division (SDSD) maintains a digital browse file of Advanced Very High Resolution Radiometer (AVHRR) data. The AVHRR instrument is aboard the TIROS‐N series of spacecraft. The instrument has five channels for viewing the earth, two channels are in the visible part of the spectrum and three are in the infrared portion
