TL;DR: Changes in the snow cover phenology led to contrasting anomalies of snow radiative forcing, which is dominated by De and accounts for 51% of the total shortwave flux anomalies at the top of the atmosphere.

Developing a composite daily snow cover extent record over the Tibetan Plateau from 1981 to 2016 using multisource data
TL;DR: In this article, a composite long-term gap-filled TP daily 5-km snow cover extent (SCE) record (TPSCE) is generated by integrating SCE from the Advanced Very High-Resolution Radiometer (AVHRR) surface reflectance climate data record (CDR) and several existing snow cover data sets, with the help of a decision tree snow cover mapping algorithm, for the period 1981-2016.

Enhanced wintertime greenhouse effect reinforcing Arctic amplification and initial sea-ice melting.
TL;DR: Strong observational evidence is reported, for the first time from long-term spatially complete satellite records, that increased cloudiness and atmospheric water vapor in winter and spring have caused an extraordinary downward longwave radiative flux to the ice surface, which may then amplify the Arctic wintertime ice-surface warming.
Bibliometric Analysis of Global NDVI Research Trends from 1985 to 2021
TL;DR: In this paper , the authors used bibliometrics and scientific mapping methods to analyze citation data retrieved from the Web of Science during 1985-2021 with Normalized Difference Vegetation Index (NDVI) as the topic.
Assessment of Sea Ice Albedo Radiative Forcing and Feedback over the Northern Hemisphere from 1982 to 2009 Using Satellite and Reanalysis Data
TL;DR: In this article, based on the satellite-retrieved long-term surface albedo product CLARA-A1 (Cloud, Albedo, and Radiation dataset, AVHRR-based, version 1) and the radiative kernel method, an estimated 0.20 ± 0.05 W m−2 sea ice radiative forcing (SIRF) has decreased in the Northern Hemisphere (NH) owing to the loss of sea ice from 1982 to 2009.
