Bienvenidos a CienciaPR, una red de recursos para todos los interesados en las ciencias y en Puerto Rico.
I am Director of the new Puerto Rico Photonics Institute, located at the Barceloneta campus of the Ana G. Mendez University System. PRPI specialize n research, education, and training in the rapidly growing fields of optics and photonics.
I am also a Senior Research Associate at the Arecibo Observatory carrying out studies of the top of the mesosphere layer (mesopause) of the Earth's atmosphere. I use a technique called lidar to remotely sense the spectra of meteor-deposited atoms at altitudes from 80 to above 100 km. This research is important to both space physics as well as climate research. I finished my PhD in 1991 at Colorado State University in Physics, studying molecular dynamics in simple liquids using nonlinear Raman spectroscopy. I have a BA in Physics from Cornell (1984).
PRPI will provide new career, research, education, and economic opportunities in Puerto Rico. Please visit our website at http://prpi.suagm.edu and like us on Facebook at http://www.facebook.com/PRPhotonics.
The mesopause is the coldest place on earth. It is the transition region from a neutral atmosphere to the ionosphere. For this reason, it has importance to both space physics and to climate research. It is where meteors burn up and spacecraft first experience turbulence upon re-entry to the earth's atmosphere. It is at the "end of the whip" for climate study, where effects in the lower atmosphere are greatly amplified (and, perhaps, inverted). Global tropospheric warming is expected to produce substantial global mesospheric cooling. Scientists have just begun exploring in detail this region once called the "ignorosphere". So we have a ways to go to catch up. Resonance lidars have made this work possible, and many of the most important developments were undertaken by the research group I was part of in the 1980s.
