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.

Ocean Ammonia Outgassing: Modulation by CO2 and Anthropogenic Nitrogen Deposition
Journal of Advances in Modeling Earth Systems, 2020 The imprint of anthropogenic activities on the marine nitrogen (N) cycle remains challenging to represent in global models, in part because of uncertainties regarding the source of marine N to the atmosphere.

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.

Dynamics of the atmosphere [PDF]
Nature, 1982 Observations of and possible explanations for the dynamics of the Venus atmosphere as revelaed by Pioneer Venus and the Venera spacecraft are discussed. An important observation was that the entire atmosphere moves in the same retrograde (westward) direction at average speeds of up to about 110 m/sec, which may be explained by zonal jets arising from ...

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.

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.

Dynamics of the Atmosphere [PDF]
Eos, Transactions American Geophysical Union, 2004 The study of atmospheric dynamics has seen an impressive expansion into many subdisciplines in the past few decades. It is only natural, then, that most textbooks published during this period have tended to focus on one of these sub‐disciplines. Atmospheric dynamics seems to be too broad a subject area to be the focus of a single text.

Atmospheric Dynamics and the Variable Transit of KELT-9 b [PDF]
Astronomical Journal, 2018 We present a spectrally and temporally resolved detection of the optical Mg i triplet at 7.8σ in the extended atmosphere of the ultra-hot Jupiter KELT-9 b, adding to the list of detected metal species in the hottest gas giant currently known. Constraints
