Hourly PWV Dataset Derived from GNSS Observations in China

open access: yesSensors, 2019
The rapid variation of atmospheric water vapor is important for a regional hydrologic cycle and climate change. However, it is rarely investigated in China, due to the lack of a precipitable water vapor (PWV) dataset with high temporal resolution ...

Advances in understanding large-scale responses of the water cycle to climate change [PDF]

open access: yes, 2020
Globally, thermodynamics explains an increase in atmospheric water vapor with warming of around 7%/°C near to the surface. In contrast, global precipitation and evaporation are constrained by the Earth's energy balance to increase at ∼2–3%/°C.

ERA5-based global assessment of irrigation requirement and validation

open access: yesPLOS ONE, 2021
While only 20% of harvested lands are actually irrigated, 40% of global agricultural production originates from irrigated areas. Therefore, assessing irrigation requirements is essential for the development of effective water-related policies for an efficient management of water resources.

The ERA5-Land soil temperature bias in permafrost regions [PDF]

open access: yesThe Cryosphere, 2020
Abstract. ERA5-Land (ERA5L) is a reanalysis product derived by running the land component of ERA5 at increased resolution. This study evaluates ERA5L soil temperature in permafrost regions based on observations and published permafrost products. We find that ERA5L overestimates soil temperature in northern Canada and Alaska but underestimates it in mid–

How Does Wind Project Performance Change with Age in the United States? [PDF]

open access: yes, 2020
Wind-plant performance declines with age, and the rate of decline varies between regions. The rate of performance decline is important when determining wind-plant financial viability and expected lifetime generation.
