2022Celebrating Arunima's Birthday on the Way to AntarcticaAugust 24, 2022 Happy Birthday, Arunima! While waiting for an ice flight in Christchurch, New Zealand, we celebrated Arunima's birthday in the hotel room 214 at Elms on August 24, 2022. This was her first birthday celebration in the Southern Hemisphere. Arunima, Jackson, Yingfei, and Dr. Chu enjoyed a birthday cake and lightened up candles. PhD student Jackson Jandreau won NASA FINESST Award as a Future InvestigatorAugust 18, 2022 Congratulations! The Science Mission Directorate (SMD) has selected the proposal "Exploring Antarctic Gravity Waves and Their Effects on Global Energy Transport Using a Decade of Lidar Observations" submitted by Jackson Jandreau and Dr. Chu to the Future Investigators in NASA Earth and Space Science and Technology: NNH21ZDA001N-FINESST within the NASA Research Announcement (NRA): Research Opportunities in Space and Earth Sciences (ROSES-2021) for funding in the total amount of $149,983. This amount is contingent on continued relevance to SMD, the availability of funds, and the Future Investigator's satisfactory progress. FINESST-21 received about 927 proposals. The Heliophysics Division reviewed 60 proposals and selected 14 proposals for awards. The Directors of SMD's funding Divisions at NASA Headquarters (or their designees) made the FINESST selections. PhD student headed to Antarctica to conduct climate research with lasersJuly 26, 2022 Arunima Prakash is preparing to study the upper atmosphere from one of the coldest and most desolate places on Earth: Antarctica. Prakash, an aerospace PhD student at the University of Colorado Boulder, is studying polar mesospheric clouds and their relation to the solar cycle and polar vortex effects. "There has been a long debate about how the solar cycle affects these clouds," Prakash said. "Past satellite observations say the sun had a dominant effect, but we're not seeing that correlation anymore. We want to study why. It could be a long-term indicator of climate change."

Her winning talk was entitled "Long-Term Lidar Observations of Polar Mesospheric Clouds in Antarctica for Studies of Solar Cycle and Polar Vortex Effects".Congratulations to Arunima Prakash for Winning the CEDAR Workshop Students Poster CompetitionJune 24, 2022 PhD student, Miss Arunima Prakash, won the Second Place Prize in the CEDAR Students Poster Competition during the CEDAR Workshop held on June 19-24, 2022 at Austin, TX. Her winning poster was entitled "Polar Vortex or Solar Cycle: Which is the major driver of 10 years of PMC variability at McMurdo, Antarctica". FYI, CEDAR stands for Coupling, Energetics, and Dynamics in the Atmospheric Region, which is a program supported by the National Science Foundation.Congratulations to Ian Geraghty for Winning the CIRES Graduate Student Research AwardMarch 29, 2022 PhD student, Ian Geraghty, won the Cooperative Institute for Research in Environmental Sciences (CIRES) Graduate Student Research Award! The CIRES Fellows voted unanimously to approve his application.Congratulations to Jackson Jandreau for Winning the AGU Outstanding Student Presentation Award (OSPA)Feb. 18, 2022 PhD student Jackson Jandreau won the American Geophysical Union (AGU) Outstanding Student Presentation Award (OSPA) for his oral presentation in AGU Fall Meeting 2021.Lidar Lab Open House to PhD applicants and undergrad students on Feb. 18, 2022Feb. 18, 2022 We were delighted to receive the visits from two PhD applicants: Bennett Bartel and Kawther Rouabhi, and from undergraduate students of Aerospace Department. Our PhD students, Arunima, Yingfei, Ian, and Jackson gave wonderful tours of the lidar labs, especially the colorful lasers and spectroscopy.2021PhD students delivered four oral talks to AGU Fall Meeting 2021Dec. 15, 2021 Jandreau and Chu published a new paper in Earth and Space Science on new lidar data processing techniquesNov. 26, 2021 $3.3 million grant to advance climate and space weather research from AntarcticaOct. 5, 2021 It is one of the coldest and most isolated places on Earth, but for a team of scientists and engineers from CU Boulder, it is the ideal location to conduct complex space-atmospheric research: the frozen tundra of Antarctica. Read MoreSpace metal detected above Boulder by CU teamOct. 1, 2021 A team at the University of Colorado detected a metal layer above Boulder, adding to research on that layer done in Antarctica. PhD student Yingfei Chen made key contributions to the discovery of the space metals above Boulder.

Read MoreHey hey hey! We got 1.03 W from RDL bare cavity alignment!September 10, 2021 This week we opened up the RDL to understand its anatomy and got much more power out! All in all the laser gods were pleased! Read MoreCollaborative Research: Fe and Na Lidar Investigations of Geospace-Atmosphere Temperature, Composition, Chemistry, and Dynamics at McMurdo, AntarcticaAugust 22, 2021 We would like to share a good news -- we received an NSF award notice on Sunday 8/22/2021 that our McMurdo renewal proposal has been funded by NSF at the full support. The total support is anticipated at ~$3.3M for 5 more years of lidar observations and science discoveries in Antarctica. Read MoreDaily sodium layers appear in Boulder's skyJune 25, 2021 At about 100 km above Earth's surface, a permanent layer of neutral sodium pulled from passing meteors rests near the top of the mesosphere. Above that, scientists have observed temporary Na layers that form and then descend back to the permanent layer. Read MoreMetals from space descend on Boulder, Colorado, at dusk and dawnJune 14, 2021 Sodium and other metals from space make regular--and irregular--landfall on Earth. Read MoreAtmospheric Metal Layers Appear with Surprising RegularityJune 2, 2021 Twice a day, at dusk and just before dawn, a faint layer of sodium and other metals begins sinking down through the atmosphere, about 90 miles high above the city of Boulder, Colorado. The movement was captured by one of the world's most sensitive "lidar" instruments and reported Tuesday in the AGU journal Geophysical Research Letters.
