Modeling equatorial plasma bubbles with SAMI3/WACCM-X: September 2017 storm
We report results from a global simulation of the September 2017 geomagnetic storm. The global model comprises the ionospheric code SAMI3 and the atmosphere/thermosphere code...- publication PDF

When will the Antarctic ozone hole recover?
The Antarctic ozone hole demonstrates large-scale, man-made affects on our atmosphere. Surface observations now show that human produced ozone-depleting substances (ODSs) are...- publication PDF

Case Studies on Convective Storms / Case Study 4, 27 July 1976: First Echo Case
On 27 July 1976, a relatively small, weak storm was investigated by the NCAR/NOAA instrumented sailplane in coordination with NCAR Queen Air 306D. The potential instability was...- publication PDF

Gargantuan hail in Argentina
On 8 February 2018, a supercell storm produced gargantuan (>15 cm or >6 in. in maximum dimension) hail as it moved over the heavily populated city of Villa Carlos Paz in...- publication PDF

Acyl peroxy nitrates link oil and natural gas emissions to high ozone...
We present measurements of ozone (O-3), acyl peroxy nitrates (APNs), and a suite of O-3 precursors made at the Boulder Atmospheric Observatory in Erie, Colorado, during summer...- publication PDF

Hydrological modeling to evaluate climate model simulations and their bias correction
Variables simulated by climate models are usually evaluated independently. Yet, climate change impacts often stem from the combined effect of these variables, making the...- publication PDF

Characterization of the long-term radiosonde temperature biases in the upper...
Radiosonde observations (RAOBs) have provided the only long-term global in situ temperature measurements in the troposphere and lower stratosphere since 1958. In this study, we...- publication PDF
