Climate impacts of parameterized Nordic Sea overflows
A new overflow parameterization (OFP) of density-driven flows through ocean ridges via narrow, unresolved channels has been developed and implemented in the ocean component of...- publication PDF

Short- and medium-term atmospheric constituent effects of very large solar...
Solar eruptions sometimes produce protons, which impact the Earth's atmosphere. These solar proton events (SPEs) generally last a few days and produce high energy particles that...- publication PDF

Simulated differences in 21st century aridity due to different scenarios of...
Aridity, defined as the ratio of precipitation (P) to potential evapotranspiration (PET) over land, is critical to natural ecosystems and agricultural production. Global climate...- publication PDF

On the (in)stability of sunspots
Context. The stability of sunspots is one of the long-standing unsolved puzzles in the field of solar magnetism and the solar cycle. The thermal and magnetic structure of the...- publication PDF

Dual-wavelength radar technique development for snow rate estimation: A case...
quantitative precipitation estimation (QPE) of snowfall has generally been expressed in power-law form between equivalent radar reflectivity factor (Z(e)) and liquid equivalent...- publication PDF

Comparison of global datasets of sodium densities in the mesosphere and...
During the last decade, several limb sounding satellites have measured the global sodium (Na) number densities in the mesosphere and lower thermosphere (MLT). Datasets are now...- publication PDF

Photoreduction of gaseous oxidized mercury changes global atmospheric...
Anthropogenic mercury (Hg(0)) emissions oxidize to gaseous Hg(II) compounds, before deposition to Earth surface ecosystems. Atmospheric reduction of Hg(II) competes with...- publication PDF

Are all flare ribbons simply connected to the corona?
We consider the observational basis for the belief that flare ribbons in the chromosphere result from energy transport from the overlying corona. We study ribbons of small...- publication PDF

Intercomparison of an ensemble Kalman filter with three- and...
This study compares the performance of an ensemble Kalman filter (EnKF) with both the three-dimensional and four-dimensional variational data assimilation (3DVar and 4DVar)...- publication PDF

The force-freeness of the solar photosphere: Revisit with new approach and...
Although it is generally believed that the solar photosphere is not magnetically force-free owing to its high plasma beta, the estimations of force-freeness using observed...- publication PDF

WRF-Chem simulations of a typical pre-monsoon dust storm in northern India:...
The impact of a typical pre-monsoon season (April-June) dust storm event on the regional aerosol optical properties and radiation budget in northern India is analyzed. The dust...- publication PDF

Quantifying the impact of the North American monsoon and deep midlatitude...
The chemical composition of the lowermost stratosphere exhibits both spatial and temporal variability depending upon the relative strength of (1) isentropic transport from the...- publication PDF

Subseasonal prediction with and without a well-represented stratosphere in CESM1
There is a growing demand for understanding sources of predictability on subseasonal to seasonal (S2S) time scales. Predictability at subseasonal time scales is believed to come...- publication PDF

Spectral analysis of ionospheric electron density and mesospheric neutral...
We use two-dimensional spectral analysis method to extract diurnal eastward zonal wavenumber 3 (E3) and westward zonal wavenumber 2 (W2) nonmigrating tide in the mesospheric...- publication PDF

Airborne intercomparison of HOx measurements using laser-induced...
The hydroxyl (OH) and hydroperoxyl (HO₂) radicals, collectively called HOx, play central roles in tropospheric chemistry. Accurate measurements of OH and HO₂ are critical to...- publication PDF
