The Lamont-Doherty Earth Observatory of Columbia University (LDEO)
located in Palisades, New York, invites applications for a
Postdoctoral Research Scientist interested in the use of
physically-informed machine learning to refine closures used in the
calculation of atmospheric radiation. The position is part of the
recent National Science Foundation Learning the Earth with
Artificial intelligence and Physics (LEAP) Science and Technology
Center (STC), <a class="moz-txt-link-freetext" href="https://leap.columbia.edu/">https://leap.columbia.edu/</a>, a large
multi-institutional center effort meant to improve climate
projections using novel artificial intelligence for better climate
adaptation.<br>
<br>
This project aims to revisit assumptions at the very core of
calculations of radiative transfer calculations. The two-stream
approximation used for computing the fate of sunlight, for example,
makes assumptions about the angular distribution of light in the sky
and how this co-varies with the light scattered from individual
particles. Assumptions made almost half a century ago remain in wide
use and are one cause of persistent radiation errors. This project
will focus on using machine learning to revisit and revise
assumptions like these, aspirationally using techniques such as
equation discovery to ensure interpretability and distill the
results for wide-spread use. The researcher is expected to present
findings at national or international scientific conferences and to
prepare publications for submission to scientific journals.<br>
<br>
The postdoctoral research scientist will collaborate with a team of
scientists including Prof. Robert Pincus (Lamont-Doherty Earth
Observatory, Columbia University), Prof. Carl Vondrick (Computer
Science, Columbia University) and Prof. Laure Zanna (Courant
Institute, New York University). The Postdoctoral Research Scientist
will join both the vibrant research community at Lamont Doherty
Earth Observatory and LEAP’s burgeoning transdisciplinary team at
the interface between machine learning/data science and climate
sciences, including research scientists, faculty members, PhD
students, undergraduate and Bridge-to-PhD researchers.<br>

<u><b style="box-sizing: inherit; font-weight: 700;">Qualifications:</b></u><br>
Candidates should have completed or be nearing completion of a Ph.D.
in in Atmospheric, Climate, or Earth System Science, Chemistry,
Applied Mathematics, Engineering, or related fields. Excellent
communication skills are important and experience with machine
learning is an advantage. One of the primary goals of LEAP is to
increase the diversity in geosciences and data science, to be on par
with the US population by the end of the Center lifetime. The Center
will take proactive steps to reach its diversity goal. We thus
particularly welcome applicants from underrepresented groups.<br>
<br>
Appointment will be for 1 year with continuation pending progress
and funding.<br>
<br>
The search will remain open for at least 30 days after the ad
appears and will continue until the position is filled.<br>
<br>
Columbia University benefits are offered with this Officer of
Research appointment.<br>
