Escalating Fire‐Driven Forest Loss in Protected Tropical Forests

Global Change Biology, Volume 32, Issue 8, August 2026.
More than 4 million hectares of protected tropical forest have been lost to stand‐replacing fire since 2001, with annual losses increasing through time in both the Americas and Africa. Protection most commonly reduced the proportion of stand‐replacing fire, but could not decouple temporal fire trends inside PAs from those outside.

Analyzing CO2 concentration changes and their influencing factors in Indonesia by OCO-2 and other multi-sensor remote-sensing data

International Journal of Digital Earth, 2018
We used OCO-2 products and considered three factors that potentially affect CO2 concentration in Indonesia: sea surface temperature (SST), forest fires and vegetation. From 2014 to 2016, CO2 concentration in Indonesia showed a trend of increase, which is

Unifying the QBO, MJO Shallow‐to‐Deep Convection Transitions, and Mesoscale Convective Systems

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract This study investigates Madden‐Julian Oscillation (MJO) convective structures to better understand how the Quasi‐biennial Oscillation (QBO) impacts MJO propagation. We find that during the QBO easterly (QBOE) phase, MJO events exhibit convective features that are highly favorable for propagation.

Invisible Ship Tracks Produce Mean‐State Cloud Microphysics Perturbation in Tropical Trade Cumulus

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Aerosol effects in cumulus‐topped boundary layers remain relatively unconstrained and drive uncertainty in climate modeling. We assess the impacts of shipping aerosol on trade cumulus, combining satellite retrievals and large eddy simulations (LES).

Impacts of Maritime Continent Forest and Peat Fires on Regional Air Quality During 2019 CAMP2Ex Using MUSICAv0

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The NASA Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex) field campaign from 24 August to 05 October 2019 observed a complex mixture of aerosols—biomass burning smoke transported from Maritime Continent (MC)/Indonesia fires to the Philippines and Metro Manila's urban pollution.

Tsunami Traveling Ionospheric Disturbances Triggered by the 29 July 2025 Mw 8.8 Kamchatka Earthquake Observed in Japan and Taiwan

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated notable seismic and tsunami waves. The total electron content (TEC) derived by more than 1,400 ground‐based global navigation satellite system (GNSS) receiving stations in Japan and Taiwan is employed to examine the spatiotemporal evolution of seismic‐ and tsunami‐traveling ionospheric ...
