Lidar Exploration of the Atmosphere, Space and Beyond

We study advanced spectroscopy principles, develop new lidar technologies, investigate the fundamental physical and chemical processes that govern the whole atmosphere, and make new discoveries in the atmosphere–space sciences. Combining lidar observations and data analyses with numerical modeling, we aim to open a new window for human exploration of the universe.

McMurdo

McMurdo Station on the New Year's Day. Arrival Heights Lidar Lab is a few miles from McMurdo, beyond the dome in the far back of the picture.

Trio

After a superb winter Zimu Li flew out and Ian Geraghty endured a 13-month deployment. Ian made sure a smooth transition to 2020 winter-overs Xianxin Li and Cissi Lin. Check out this NPR article about a beautiful cake modeled after our lidar!

SSW Discussion

At Boulder PhD students Amanda Steckel and Jackson Jandreau work hard on science research while taking classes. They learn a lot from discussions with atmospheric scientist Dr. Lynn Harvey.

We always welcome new members and scientific collaborations!

2019 Chu Group

Our group photo on Boulder campus in Fall 2019. From front right, Jackson Jandrea (Smead Fellow), Zimu Li (2019 Winter-Over Scientist), Nate O'Neill (Research Assistant), Dr. Mike Jones (Senior Scientist), Dr. Dongsong Sun (Visiting Professor). From the back left, Zhuoying Chen (Undgrad Research Assistant), Dr. Cissi Lin (2020 Winter-Over Scientist), Amanda Steckel (PhD Graduate Research Assistant), Xianxin Li (2020 Winter-Over Scientist), Arunima Prakash (Graduate Research Assistant), and Dr. Chu.
Three team members are missing from this this group photo. Ian Geraghty (2019 Winter-Over Scientist) was running lidars in Antarctica, Nik Sinkola (Engineering Expert) was on travel, and Manuel Lindo (Undergrad Research Assistant) was attending a class. They are shown in the following two photos.

Antarctic Thanksgiving

2019 Fall

We had a fun moment with this famous statue in front of the Old Main building in September 2019. From the front right, Arunima Prakash, Manuel Lindo, Nik Sinkola, and Dr. Mike Jones. From the back left, Dr. Cissi Lin, Amanda Steckel, Jackson Jandreau, Nate O'Neill, Zimu Li, and Dr. Chu.

Years of creativity and hard work have achieved many scientific discoveries and breakthroughs, and many past and present group members have made great contributions. Below are historic pictures for our beautiful memories of the journey.

This is an energetic group! Many members have traveled to the end of the world to make lidar observations in Antarctica.
10 students (Zhibin Yu, Brendan Roberts, Weichun Fong, Cao Chen, Jian Zhao, Ian Barry, Zhengyu Hua, Dongming Chang, Zimu Li, and Ian Geraghty) have braved through the harsh Antarctic winters from 2011 through 2019!

Winter Over

Dr. Zhibin Yu and Mr. Brendan Roberts were the first two winter-over lidar scientists in 2011 and 2012

Winter-over students 2013 and 2014

Dr. Weichun Fong and Dr. Cao Chen braved through winters 2013 and 2014

Winter-over 2015 and 2016

We are excited not only by the lovely penguins, but also by the new science discoveries we have made in the polar atmosphere and space from the McMurdo lidar data. More details can be found in our Publications.

Boulder is home to a vibrant community of scientists and engineers and houses some of the world's most renowned environmental science institutes and facilities. Many of our residents allow this exploratory spirit to carry over into their free time, with vast expanses of open space in and around the community for hiking, biking, skiing and other outdoor activities.

Energetic group 2013

Our Lidar Group in October 2013 on Boulder Campus.

Besides making new science discoveries, these creative researchers are also excited by making innovations in lidar technologies and developing the next-generation lidar instruments. New lidars have been or are being developed on our Boulder campus.

Lidar

Creative students Zhibin Yu and John A. Smith “painted” LIDAR with the STAR Na Doppler lidar at the Table Mountain Lidar Facility, north of Boulder.

Lidar research carries us to see wonders in the world ...

McMurdo Aurora

Spectacular aurora display over Arrival Heights near McMurdo, Antarctica when Zhibin Yu was operating our Fe Boltzmann lidar there on May 28, 2011.

Creativity, dedication, and persistency paid off, as many PhD students earned PhD degrees and honors, such as the first place prizes at the National Science Foundation (NSF) CEDAR Students Poster Competitions, and landed up top jobs such as faculty members, NASA scientists, industry engineers, research leaders, and Antarctic explorers ...

Lidar PhDs

Lidar "geeks" Dr. Zhibin Yu and Dr. John Smith earned their PhD degrees in December 2014 with Professor Xinzhao Chu in Department of Aerospace Engineering Sciences

CEDAR Prize

CEDAR science community recognized and honored the lidar team's achievements with a CEDAR Prize Lecture Award to Professor Xinzhao Chu

CEDAR Prize Lecture

CEDAR prize lecture was given by Dr. Chu on June 18, 2019 at Santa Fe, NM
