Why doesn't the observed fieldâaligned current saturate with increasing...
Theoretical studies indicate that electric potential saturation in a polar cap ionosphere is regulated by the limited reconnection rate at the magnetopause associated with...- publication PDF

The Central Amazon biomass sink under current and future atmospheric CO2:...
There is large uncertainty whether Amazon forests will remain a carbon sink as atmospheric CO2 increases. Hence, we simulated an old-growth tropical forest using six versions of...- publication PDF

Generation and propagation of interia-gravity waves from vortex dipoles and jets
This study investigates gravity wave generation and propagation from jets within idealized vortex dipoles using a nonhydrostatic mesoscale model. Two types of initially balanced...- publication PDF

The SOA/VOC/Nox system: An explicit model of secondary organic aerosol formation
Our current understanding of secondary organic aerosol (SOA) formation is limited by our knowledge of gaseous secondary organics involved in gas/particle partitioning. The...- publication PDF

Tracking mesoscale convective systems in IMERG and regional variability of...
Mesoscale convective systems (MCSs) constitute only a fraction of convective systems in the tropics but significantly impact tropical weather and global climate. Early studies...- publication PDF

Evaluation of the emission inventory for large point emission sources in...
One of the major issues in determining a region's air quality is the uncertainty of large point sources (LPSs) emissions, which significantly affect the local-regional air...- publication PDF
