HRD scientists participate in the 101st American Meteorological Society Annual Meeting

The Annual Meeting is the world’s largest yearly gathering for the weather, water, and climate community. It brings together great minds from a diverse set of scientific disciplines – helping attendees make career-long professional contact and life-long friends while learning from the very top people in the atmospheric sciences. The 101st AMS Annual Meeting took place virtually from 10 to 15 January, 2021. All the sessions and posters are available to attendees and will be available to the general community by April, 2021.
