About Reuniwatt:

Born under the sun of Reunion Island (Indian Ocean), Reuniwatt is a leading actor with a proven expertise in cloud and solar irradiance observation and forecasting. We offer reliable products and services for various sectors including renewable energy and atmospheric science. Reuniwatt has offices in Reunion Island, Paris, and Toulouse. We have placed a particular emphasis on solar energy forecasting, while developing cutting-edge solutions to improve minute-scale, hour-scale, and day-scale forecasts of cloud cover and solar irradiance. Our clients are growing worldwide, and our forecasts are used for the most demanding and prestigious operations (biggest power plants in the world, massive assets management, etc.). Innovation being the cornerstone of our strategy, more than 300,000 hours of internal R&D have been invested so far, resulting in 4 patents and more than 80 scientific publications.

Context:

Cloud Optical Depth, defined as the optical thickness between the top and the bottom of a cloud, is of great interest in several fields such as climate studies, solar energy forecasting or free space optical communication. Yet, to date, Cloud Optical Depth is a poorly observed climate variable. Several instruments and methods can be used to measure Cloud Optical Depth from the ground but there is a need for more accurate and automatic measurements. Those instruments include passive instrument such as photometers or all-sky imagers and active instrument such as cloud radar or Lidar.

Objective:

Identify, implement and compare Cloud Optical Depth retrieval methods both from passive (e.g. sky imager) and active (e.g. LIDAR) instruments.

Activities:

More specifically, your activities will be concerning :
•    A review of literature of existing methods for measuring Cloud Optical Depth from the ground
•    Implementation and meticulous testing of the identified methods on measurement datasets that may include visible/thermal sky imagers, ground based LIDAR, cloud radar, etc.
•    Writing a detailed report of your developments.

Qualifications:

Bachelor/Master of Science in one of the following fields: Meteorology, Atmospheric Science, Optics, Computer Science.

Skills:

We are looking for a skilled and motivated intern interested in atmospheric science, computer programming and optics.

Familiarity with Lidar data would be a plus.

Experience with one or more of the following tools would be a plus: Python, shell scripting.

Location:

The intern will be based in Reunion Island (St Denis).

Duration:

6 months beginning in 2nd quarter of 2020.

Compensation:

€700 raw/month (~€650/month), 1 round-trip flight ticket to Reunion Island.

Contact:

Send your CV and cover letter to jobs@reuniwatt.com with the following subject: "COD intercomparison".

N.B:

In France, an internship has more legal constraints than in some other countries. A contract between the company, the intern, and a university must be established. Thus, the intern MUST be enrolled student at a university.
