The most promising traits are associated with productivity and resistance to Sphaerulina musiva -induced canker while wood density can be selected for secondarily. A minimum age of 8 years is reliable to select fast-growing resistant clones in northern climates. Productivity, wood density, and disease resistance of hybrid poplar clones are important traits when selecting for cultivation at an industrial scale. We studied 1978 hybrid poplar clones from 63 families, bred from poplars native (Populus balsamifera and Populus deltoides) and non-native to Canada from the Aigeiros and Tacamahaca sections, to improve economically important traits for plantations in northern Alberta.

Seasonal Deformation of Permafrost in Wudaoliang Basin in Qinghai-Tibet Plateau Revealed by StaMPS-InSAR / Ping Lu in Marine geodesy, Vol 43 n° 3 (May 2020)  

Public [article]  inMarine geodesy > Vol 43 n° 3 (May 2020) . - pp 248 - 268 Titre : Seasonal Deformation of Permafrost in Wudaoliang Basin in Qinghai-Tibet Plateau Revealed by StaMPS-InSAR Type de document : Article/Communication Auteurs : Ping Lu, Auteur ; Jiangping Han, Auteur ; Tong Hao, Auteur ; et al., Auteur Année de publication : 2020 Article en page(s) : pp 248 - 268 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image radar et applications [Termes descripteurs IGN] climat froid [Termes descripteurs IGN] image Sentinel-SAR [Termes descripteurs IGN] Tibet Résumé : (Auteur) Permafrost is extremely sensitive to variance in external hydrothermal conditions. InSAR has advantages in monitoring surface deformation with decent temporal and spatial resolution as well as millimeter precision. In particular, the StaMPS-InSAR method can remove the disturbances of inaccurate digital elevation model (DEM), atmospheric delays and spatiotemporal decorrelation for an accurate estimation of temporal surface deformation. In this paper, a set of ascending and descending Sentinel-1 imageries spanning from March 2017 to June 2018 were acquired and processed by StaMPS-InSAR in order to investigate dynamic changes of permafrost in Wudaoliang Basin, Qinghai-Tibet Plateau (QTP). The results revealed that significant seasonal changes of permafrost, namely subsidence (thawing) in summer and uplift (freezing) in winter, can be observed throughout the Wudaoliang region. This study shows the StaMPS-InSAR analysis on Sentinel-1 datasets has great potential in regional permafrost investigation.

In this paper, the cloud detection algorithm for the Moderate Resolution Imaging Spectrometer (MODIS) is evaluated with model simulations and satellite data collocated with radar/lidar observations at three Arctic and Antarctic stations. Results show that the current MODIS cloud mask algorithm performs well in polar regions during the day but does not detect more than 40% of the cloud cover over the validation sights at night. Two new cloud tests utilizing the 7.2 um water vapor and 14.2 um carbon dioxide bands, one new clear-sky test using the 7.2 um band, and changes to the thresholds of several other tests are described. With the new cloud detection procedure, the misidentification of cloud as clear decreases from 44.2% to 16.3% at the two Arctic stations, and from 19.8% to 2.7% at the Antarctic station.

A significant component is the Earth's cryosphere, as glacier- related, feedback mechanisms govern atmospheric, hydrospheric and lithospheric response. Predicting the human and natural dimensions of climate-induced environmental change requires global, regional and local information about ice-mass distribution, volumes, and fluctuations. The Global Land-ice Measurements from Space (GLIMS) project is specifically designed to produce and augment baseline information to facilitate glacier-change studies. This requires addressing numerous issues, including the generation of topographic information, anisotropic-reflectance correction of satellite imagery, data fusion and spatial analysis, and GIS-based modeling. Field and satellite investigations indicate that many small glaciers and glaciers in temperate regions are downwasting and retreating, although detailed mapping and assessment are still required to ascertain regional and global patterns of ice-mass variations. Such remote sensing/GIS studies, coupled with field investigations, are vital for producing baseline information on glacier changes, and improving our understanding of the complex linkages between atmospheric, lithospheric, and glaciological processes.
