Focus on the impact of climate change on wetland ecosystem and carbon dynamics [PDF]
, 2016 The renewed growth in atmospheric methane (CH4)since 2007 after a decade of stabilization has drawn much attention to its causes and future trends. Wetlands are the single largest source of atmospheric CH4.

A new airborne laser-induced fluorescence instrument for in situ detection of formaldehyde throughout the troposphere and lower stratosphere [PDF]
Atmospheric Measurement Techniques, 2015 The NASA In Situ Airborne Formaldehyde (ISAF) instrument is a high-performance laser-based detector for gas-phase formaldehyde (HCHO). ISAF uses rotational-state specific laser excitation at 353 nm for laser-induced fluorescence (LIF) detection of HCHO ...

Observationally constrained projection of Afro-Asian monsoon precipitation
Nature Communications, 2022 A new study shows the latest climate models tend to overestimate future Afro-Asian monsoon rainfall and runoff due to present-day biases of warming patterns. By constraining biases, the rainfall increase is 70% of the raw projection.

Increased impact of heat domes on 2021-like heat extremes in North America under global warming
Nature Communications, 2023 The heat dome explains about 55% of the 2021 Western North American high temperatures. The intensity of heat extremes associated with such circulations are increasing faster than background global warming due to soil moisture feedbacks.

Changes in the aerosol direct radiative forcing from 2001 to 2015: observational constraints and regional mechanisms [PDF]
Atmospheric Chemistry and Physics, 2018 We present estimates of changes in the direct aerosol effects (DRE) and its anthropogenic component (DRF) from 2001 to 2015 using the GFDL chemistry–climate model AM3 driven by CMIP6 historical emissions.

Turbulent helium gas cell as a new paradigm of daily meteorological fluctuations? [PDF]
, 1997 We compare the spectral properties of long meteorological temperature records with laboratory measurements in small convection cells. Surprisingly, the atmospheric boundary layer sampled on a daily scale shares the statistical properties of temperature ...
