Abstract: Key Points Ruosteenoja et al.'s () claim that supersaturation in the surface atmosphere is unrealistic and necessarily spurious and incorrect Supersaturations are a reality that an increasing number of atmospheric models can reproduce even in the surface atmosphere Modelers should not artificially cap relative humidity at 100% when feeding climate model archives

Abstract: The Application Of Phosphorus (P) Fertilizer To Agricultural Soils Increased By 3.2 % Annually From 2002 To 2010. We Quantified In Detail The P Inputs And Outputs Of Cropland And Pasture And The P Fluxes Through Human And Livestock Consumers Of Agricultural Products On Global, Regional, And National Scales From 2002 To 2010. Globally, Half Of The Total P Inputs Into Agricultural Systems Accumulated In Agricultural Soils During This Period, With The Rest Lost To Bodies Of Water Through Complex Flows. Global P Accumulation In Agricultural Soil Increased From 2002 To 2010 Despite Decreases In 2008 And 2009, And The P Accumulation Occurred Primarily In Cropland. Despite The Global Increase In Soil P, 32 % Of The World's Cropland And 43 % Of The Pasture Had Soil P Deficits. Increasing Soil P Deficits Were Found For African Cropland Vs. Increasing P Accumulation In Eastern Asia. European And North American Pasture Had A Soil P Deficit Because The Continuous Removal Of Biomass P By Grazing Exceeded P Inputs. International Trade Played A Significant Role In P Redistribution Among Countries Through The Flows Of P In Fertilizer And Food Among Countries. Based On Country-scale Budgets And Trends We Propose Policy Options To Potentially Mitigate Regional P Imbalances In Agricultural Soils, Particularly By Optimizing The Use Of Phosphate Fertilizer And The Recycling Of Waste P. The Trend Of The Increasing Consumption Of Livestock Products Will Require More P Inputs To The Agricultural System, Implying A Low P-use Efficiency And Aggravating P-stock Scarcity In The Future. The Global And Regional Phosphorus Budgets And Their Pues In Agricultural Systems Are Publicly Available At Https://doi.pangaea.de/10.1594/pangaea.875296.

. (2018). How Does Ground Clutter Affect CloudSat Snowfall Retrievals Over Ice Sheets? (Vol. 16).
Abstract: CloudSat has provided the first spaceborne snowfall observations in polar regions. Nevertheless, CloudSat retrievals may be affected by ground clutter even if the snowfall rate at the surface is estimated from the reflectivity measured at about 1200 m above land/ice surface. In this study, the impact of ground clutter contamination on CloudSat snowfall retrievals over the Antarctic and Greenland ice sheets is investigated. Our results suggest that ground clutter affects CloudSat snowfall observations over some areas, particularly over complex terrain such as mountain ranges and fjords. Over these areas, the snowfall rates deduced from CloudSat observations can be, therefore, significantly overestimated. This has implications when developing snowfall climatologies from CloudSat products.
