Yield estimation of summer maize based on multi‐source remote‐sensing data

Agronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022
Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution

Fine particulate matter (PM2.5) trends in China, 2013–2018: separating contributions from anthropogenic emissions and meteorology

Atmospheric Chemistry and Physics, 2019
. Fine particulate matter (PM2.5) is a severe air pollution problem in China. Observations of PM2.5 have been available since 2013 from a large network operated by the China National Environmental Monitoring Center (CNEMC).

Moisture sources tracking of a cold vortex rainstorm over Northeast China using FLEXPART

Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
A typical Northeast Cold Vortex (NECV) rainstorm on July 25, 2016 occurred under a favorable atmospheric circulation background. Target particles that make significant contributions to this NECV rainstorm mainly came from the Indo‐China Peninsula, South China Sea, Bay of Bengal, and central China on relatively low levels. The largest water vapor uptake

How Asian slum emissions impact local microclimates in polluted air masses

Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
Cook stove emissions over urban sprawl in South India and expected microphysical implications. Combustion‐mediated soot and black carbon from biomass burning in shantytowns modulate the local cloud cover. Abstract Urban sprawl comprising densely populated slums over South Asian cities yields copious amounts of soot and black carbon from archaic cooking

Meteorology-driven variability of air pollution (PM1) revealed with explainable machine learning

Atmospheric Chemistry and Physics, 2020
. Air pollution, in particular high concentrations of particulate matter smaller than 1 µm in diameter (PM1), continues to be a major health problem, and meteorology is known to substantially influence atmospheric PM concentrations.

Recent decrease in inner‐core rain rate of tropical cyclones over the western North Pacific

Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
The decreasing trend in inner‐core rain rate of tropical cyclones over the western North Pacific. Abstract The tendency in tropical cyclone (TC) rainfall is of great concern due to its remarkable contribution to global precipitation and extreme rainfall events.

Predictability of European winter 2020/2021: Influence of a mid‐winter sudden stratospheric warming

Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
Boreal winter 2020/2021 was characterised by a negative North Atlantic Oscillation (NAO) pressure pattern, yet the signals from the ensemble mean of many seasonal forecast systems were for a positive NAO. In this letter we focus on the GloSea5 seasonal forecast system and investigate if there is any evidence for forecast error, or whether the ...

Global modeling of tropospheric chemistry with assimilated meteorology : Model description and evaluation

, 2001
We present a first description and evaluation of GEOS-CHEM, a global three- dimensional (3-D) model of tropospheric chemistry driven by assimilated meteorological observations from the Goddard Earth Observing System (GEOS) of the NASA Data Assimilation ...

Error investigation of rain retrievals from disdrometer data using triple colocation

Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022
This work aims to provide error estimates of three in‐situ precipitation sources applying the triple colocation statistical method. The latter has the enviable advantage to succeed in characterizing the uncertainties of co‐located measurements being compared each other, without requiring the knowledge of the true value, which is often unknown.

Downward Trend in Methane Detected in a Northern Colorado Oil and Gas Production Region Using AIRS Satellite Data

Earth and Space Science, 2022
The oil and gas (O&G) sector is estimated to be the largest contributor to anthropogenic methane (CH4) emissions in Colorado. Since 2004, the State of Colorado has implemented multiple regulations to significantly reduce emissions from the O&G sector ...
