Way, JoBea, 1997, "Winter and Spring Thaw as Observed with Imaging Radar at BOREAS", https://hdl.handle.net/2014/22831, USA, JPL Open Repository
In the boreal forest region and for coniferous forest species, the summer frost free period bounds the growing season length (Walter et Breckle 1993). For both coniferous and deciduous trees, their grown potential is further limited by their mineral and water uptake. |

Jonathan Jiang, 2020, "Wintertime particulate matter decrease buffered by unfavorable chemical processes despite emission reductions in China", https://doi.org/10.48577/jpl.LSS0I9, Geophysical Research Letters, JPL Open Repository
Extreme and persistent haze events frequently occur during wintertime China. While recent emissions reductions reduced annual mean fine particulate matter (PM2.5) concentrations over eastern China, their effectiveness on wintertime PM2.5 trend remains uncertain. We use observatio... |
