Diurnal Cycle of Passive Microwave Brightness Temperatures over Land at a Global Scale by Zahra Sharifnezhad, Hamid Norouzi, Satya Prakash, Reginald Blake, Reza Khanbilvardi

“…Furthermore, seasonal variations in the diurnal TB range for different land cover types show a more consistent result over the Southern Hemisphere than over the Northern Hemisphere. The calibrated TB diurnal cycle may then be used to consistently estimate the diurnal cycle of land surface emissivity. …”

Reconstruction of Vegetation Index Time Series Based on Self-Weighting Function Fitting from Curve Features by Wenquan Zhu, Bangke He, Zhiying Xie, Cenliang Zhao, Huimin Zhuang, Peixian Li

“…The results indicate that the weighted function fitting with SWCF outperformed the corresponding unweighted function fitting with the root-mean-square error (RMSE) significantly reduced by 26.82–52.44% (<i>p</i> < 0.05), and it also outperformed the Savitzky–Golay filtering with the RMSE significantly reduced by 13.98–54.04% (<i>p</i> < 0.05) for 270 sample points selected in mid-high latitudes of the Northern Hemisphere. Moreover, SWCF showed excellent robustness and applicability in regional applications.…”

High potential for loss of permafrost landforms in a changing climate by Olli Karjalainen, Miska Luoto, Juha Aalto, Bernd Etzelmüller, Guido Grosse, Benjamin M Jones, Karianne S Lilleøren, Jan Hjort

“…We deploy a statistical ensemble approach to model, for the first time, the current and potential future environmental conditions of three typical permafrost landforms, pingos, ice-wedge polygons and rock glaciers across the Northern Hemisphere. We show that by midcentury, the landforms are projected to lose more than one-fifth of their suitable environments under a moderate climate scenario (RCP4.5) and on average around one-third under a very high baseline emission scenario (RCP8.5), even when projected new suitable areas for occurrence are considered. …”

Future Directions in Eubalaena spp.: Comparative Research to Inform Conservation by Rob Harcourt, Julie van der Hoop, Scott Kraus, Emma L. Carroll, Emma L. Carroll

“…All three extant right whales [Eubalaena australis (Southern; SRW), glacialis (North Atlantic; NARW), and japonica (North Pacific; NPRW)] were heavily exploited, and the status of the two northern hemisphere species remains precarious. Recently, limited gains made by the NARW have been reversed and urgent changes to management approaches are needed if extinction is to be averted. …”

Asynchronous glacial dynamics of Last Glacial Maximum mountain glaciers in the Ikh Bogd Massif, Gobi Altai mountain range, southwestern Mongolia: aspect control on glacier mass bal... by P. Khandsuren, Y. B. Seong, H. H. Rhee, C.-H. Lee, M. A. Sarikaya, J.-S. Oh, K. Sandag, B. Y. Yu

Forests dominate the interannual variability of the North American carbon sink by Yoichi P Shiga, Anna M Michalak, Yuanyuan Fang, Kevin Schaefer, Arlyn E Andrews, Deborah H Huntzinger, Christopher R Schwalm, Kirk Thoning, Yaxing Wei

“…We find that deciduous broadleaf and mixed forests are the primary regions responsible for North American NEE IAV, which differs from the ecoregions identified for the globe and Northern Hemisphere. We also find that a suite of terrestrial biosphere models (TBMs) do not agree on the dominant biome contributing to NEE IAV, with TBMs falling along an apparent spectrum ranging between those with IAV dominated primarily by forested ecosystems to those with IAV dominated by non-forested ecosystems. …”
