===Ozone photochemistry===
His PhD thesis of 1964 concerned the interactions of ozone photochemistry, [[radiative transfer]] and the dynamics of the middle atmosphere. This formed the basis of his seminal ''Radiative and Photochemical Processes in Mesospheric Dynamics'' that was published in four parts in the ''[[Journal of the Atmospheric Sciences]]'' between 1965 and 1966.<ref>{{cite journal | url = http://eaps.mit.edu/faculty/lindzen/raphprmdy1.pdf | last1 = Lindzen | first1 = Richard S | first2 = RM | last2 = Goody | year = 1965 | title = Radiative and photochemical processes in mesospheric dynamics: Part I.

Lindzen's work on ozone photochemistry has been important in studies that look at the effects that anthropogenic [[ozone depletion]] will have on climate.<ref>See for instance the widely cited study {{cite journal |url=http://www.gfdl.gov/~gth/netscape/1980/sbf8001.pdf |last1=Fels |first1=SB |first2=JD |last2=Mahlman |first3=MD |last3=Schwarzkopf |first4=RW |last4=Sinclair |year=1980 |title=Stratospheric Sensitivity to Perturbations in Ozone and Carbon Dioxide: Radiative and Dynamical Response |journal=J.
