The PRPI Director continues his research program at the Arecibo Observatory, probing the climatology, dynamics, and chemistry of the upper mesosphere and lower thermosphere (80-110 km altitude) using resonance Doppler lidar. Among the areas of interest are MLT temperature climatology, the nature of sporadic metal layers, and metals in the thermosphere (>110 km altitude).

PRPI has received the following research grants:

NSF-1126123 MRI-Acquisition: Puerto Rico Atmospheric Major Research Laser Instrumentation Program (PR-LASER) This grant is to acquire a new transmitter laser system for the Arecibo Observatory resonance Doppler lidar. Period of activity 8/2011-7/2013.

MIT Draper Lab URAD Contract entitled: "Development of remote sensing instrument derived from Draper intertial systems optics expertise".
