the jcsda summer colloquium on satellite data assimilation
July 12-august 7, 2015 - Fort collins, CO

The NASA/NOAA/DoD Joint Center for Satellite Data Assimilation (JCSDA) is pleased to announce a Summer Colloquium on Satellite Data Assimilation in 2015 engaging graduate students and individuals with early postdoctoral appointments in the science of data assimilation for the atmosphere, land and oceans. The program will include internationally recognized experts in data assimilation, satellite data use and assimilation, along with opportunities for students to interact with the lecturers in an informal setting. The objective of the program is to foster the education of the next generation of data assimilation scientists.

Date and Location

The JCSDA Summer Colloquium on Satellite Data Assimilation will take place in Fort Collins, CO from July 27 to August 7, 2015.

Colloquium Topics

The following topics will be covered during the Colloquium:

  • Data assimilation fundamentals including variational and ensemble techniques

  • Satellite data applications including infrared and microwave

  • Satellite data assimilation techniques

  • Overview of atmospheric, ocean and land data assimilation

  • Overview of the global observing system

Graduate students who expect to receive their Ph.D. in the physical, environmental, atmospheric or related science prior to June 2016 are invited to apply as well as individuals with no more than two years of postdoctoral experience at the time of the Colloquium will be given priority but consideration will also be given to to other year Ph.D. candidates and Masters Candidates as well. Preference will be given to applicants with US citizenship, permanent residency or a valid work/student visa. However, international participation is welcomed if sponsorship can be provided by the home country.

Application Process

There is no application form. Qualified applicants are encouraged to apply by sending the following material:

  • Curriculum vitae

  • Statement of interest (no more than one page) with a one-page summary of the applicant's doctoral research

  • Three supporting letters from faculty members

The above documents should be sent via email by April 30, 2015 to Dr. James Yoe and Ms. Rene Brown.

Candidates will be selected competitively based upon documentation they provide and will be notified of the disposition of their application in April or May.

Financial Support

Travel support to and from the Colloquium, lodging expenses, and per diem will be provided for the two-week program for approximately 15 participants. Additional applicants may be invited to participate, but they will need to provide their own financial support.


The colloquium will be held at the Cooperative Institute for Research in the Atmosphere (CIRA) at Colorado State University in Fort Collins, Colorado. Detailed logistical information for the Colloquium will be provided to the individuals selected for participation at the time they are notified of their selection.
