A Bow of the Head for a Great Lidar Scientist and an Even Better Person: Dr. Rod Frehlich

I'm sad to post that Dr. Rod Frehlich, lidar phenomenology and signal processing guru, passed away last Friday in Boulder, Colorado. Rod finally lost his long and hard battle that had been a great ordeal for him and his loving wife Ilana.

It is sadly ironic that Rod's demise originated with a brain tumor, given that his extraordinary mind was what set him apart from his peers in the niche communities that are wave propagation, turbulence measurement, and lidar and radar signal processing and data analysis. A major portion of Rod's career work focused on coherent Doppler wind lidar and he provided breakthrough clarity on the underpinnings of those systems and how to optimize their performance, optimally assimilate their data, and apply them to challenges in meteorology and boundary layer physics.
Rod was kind enough to include me as a coauthor on a few of his numerous journal and conference papers.  We would dole out a small bit of data from one of our development or production lidar systems, and Rod would 'lay hands' on it, generating important new insights and results. Through the many years of his support to several CTI programs, I knew Rod to be perpetually upbeat and enthusiastic. It was often a challenge to wrap up our phone conversations. Those of you who ever discussed a technical topic on the phone with Rod know exactly what I mean.  He was a positive energy guy with unmatched skills and insights who always gave more than he received.

Rod spent most of his career with the University of Colorado at Boulder's Cooperative Institute for Research in Environmental Sciences (CIRES) and since 1998 simultaneously served as a Scientific Visitor to the National Center for Atmospheric Research. While he made important contributions to both these institutions, he really was an asset for the greater coherent lidar community, as well as several related communities. And as such, the world has experienced a notable and significant setback with his passing.

A dance party will be held in Boulder sometime in the near future to celebrate Rod's life. Rod and Ilana's passion for dance was legendary, so such a memorial is most fitting.

Godspeed, Rod Frehlich.

How very sad to hear. I still chuckle over the series of funny papers: Sonnenshein and Horrigan became "Sunshine in Oregon", Frehlich and Kavaya became "Frolick in Hawaii" and with a minor contribution by yours truly Suni and Kavaya became "Sunny in Hawaii". Rod was truly a great person.

I met Rod while we were both third year undergrad students at the University of Saskatchewan. We were room mates and house mates for several years.
I remember Rod most for his great sense of humor. He did not seem to mind very much when we moved his glasses while he was asleep. Upon awakening he had a difficult time finding them. One time he put a live bat (taken from an attic in the physics buiding I believe)in my bedroom.

Dude - great comment and stories! Demonstrates Rod's sense of humor as well as his thick skin. You definitely need both if you choose to dabble in physics and especially lidar.

I met Rod 20 years ago. He was a very special person. Not only was he a great scientist, but he was an upbeat gentleman with a great sense of humor. It was always not only fun, but also interesting to spend time with him.This is truly a great loss for his family, friends, colleagues, and scientists.

Little did we know, in the dance community, of the genius of which you speak. Our love was for a favorite dance partner, a fun, light-hearted friend, and a leader in the dance community. Rod was modest about his accomplishments. Thank you, Steve, for enlightening us.

Melba -
What a great and neat perspective! How important it is to maintain a flexible balance in life. Rod obviously achieved that and made every day count.

I know Rod and Ilana from dancing with them for years. So cool to read a bit about another part of Rod's life. Thanks for writing this! Sounds like Rod will be missed in more than one community.

I, to, enjoyed Rod' sense of humor......and I can remember one time talking to him about his color radar work, and he explained it to me in very simple layman's terms, as though he was really enjoying talking about it to someone who know very little....He always had a smile on his face, and always asked me what I was up to when he saw me....I felt a lot of warmth from him....

Thank you for posting this. I met Rod over 23 years ago, when I was thinking of moving to Colorado and danced with him. After I moved here, he'd spin me around and tease me about getting dizzy. I loved his sense of humor and loved watching him and Ilana dance together. Their dancing was exquisite. We'll all miss Rod.

Steve, A very nice tribute to Rod. He was a great resource for me on the intricacies of lidar, and always willing to spend time to pass on his knowledge and to share his insights. We will miss him.

There is a candle in the window for you dear friend and mentor. I first met you when I was all of 13 years old in Wilkie, Sask. You made a big impact on me then and throughout my life. You loved to dance way back then- all those weekend live bands that would come out from Saskatoon! There is a dumbness in my heart for you. "Gonna recommend you to the Spirit in the sky!" Hope to see you one day on the other side.

You are with me in your afterlife and I feel it. I know when you are here! Love it! Put a candle in the window- you know that.

I've known Rod for many years from dancing in Boulder. I am not surprised to hear about his excellence and enthusiasm in his primary endeavor; just what I'd expect from the Rod I knew. He was bright, conscientious, generous, upbeat, humorous - and what a fun dance partner and leader! He and Ilana have been great leaders in our beloved dance community. I will greatly miss him. Thanks, Steve, for this posting - an insight into a side of Rod of which I've had only a glimpse.

Though I met Rod for just a few times only, I am deeply impressed by his scientific insights. Many of my works are based on the firm foundation set by him. We will miss him.

Sorry to hear of his passing Had a great visit with him at last summers celebration in Wilkie Saskatchewan. Had not seen him since leaving Saskatchewan in 1963. We went to school together
and were also related My condolances to the family

I just received an email from a friend who happened to be on a boat on the Danube River with Ilana recently. When they discovered that they both knew me, Ilana shared the news of Rod's death. Rod has been a friend since 1976 -- we were ballroom dance partners in San Diego. He even proposed all those long years ago. He was truly a gentlemen and a scholar and a dear, dear soul.
