Impacts of urban morphology on sensible heat flux and net radiation exchange

Urban morphology affects the sensible heat flux and net radiation exchange which can alter urban heat mitigation plans. This study first parameterized the geometric effects on the net radiation, and then calculated the net radiation and sensible heat flux in the urban landscape of Hong Kong. Considering that the sensible heat flux is the main...

Characterizing the thermal effects of vegetation on urban surface temperature

Vegetation is important for urban heat mitigation. The cooling intensity of vegetation is affected by background climate and urban design. How to evaluate vegetation cooling efficiency under different climate conditions is still an issue open to discussion. In this study, a normalized indicator of urban vegetation cooling efficiency (NVCE) is...

Global soil moisture data fusion by Triple Collocation Analysis from 2011 to 2018

Surface Soil Moisture (SSM) information is needed for agricultural water resource management, hydrology and climate analysis applications. Temporal and spatial sampling by the space-borne instruments designed to retrieve SSM is, however, limited by the orbit and sensors of the satellites. We produced a Global Daily-scale Soil Moisture Fusion...

Impacts of the Silk Road pattern on the interdecadal variations of the atmospheric heat source over the Tibetan Plateau

This study aimed to investigate the relationship between the boreal summer Silk Road Pattern (SRP) and the atmospheric heat (<Q1>) over the Tibetan Plateau (TP) region, using 5 reanalysis datasets over the period 1979–2019. Our results indicate an interdecadal change of boreal summer SRP over the Eurasian region, with a regime shift in...

Constructing dataset of classified drainage areas based on surface water-supply patterns in High Mountain Asia

The High Mountain Asia (HMA) region, ranging from the Hindu Kush and Tien Shan in the west to the Himalaya in the south with an altitude between 2000 and 8844 m, holds the largest reservoir of glaciers and snow outside Earth Polar Regions. In the last decades, numerous glaciers and lake areas there have undergone tremendous changes with water...

Improving the AMSR-E/NASA soil moisture data product using in-situ measurements from the Tibetan Plateau

The daily AMSR-E/NASA(the Advanced Microwave Scanning Radiometer-Earth Observing System/the National Aeronautics and Space Administration) and JAXA (the Japan Aerospace Exploration Agency) soil moisture (SM) products from 2002 to 2011 at 25 km resolution were developed and distributed by the NASA National Snow and Ice Data Center Distributed...
