Dan Braithwaite
Programmer / Analyst III
The Center for Hydrometeorology & Remote Sensing
B.S. Computer Engineering, The University of Arizona, Tucson, AZ, 1986

Specialization: Programming and Software development

Dan brings over 22 years of extensive experience as a systems analyst using a wide variety of programming environments and tools to CHRS.

He has worked with Professor Soroosh Sorooshian and his research team on the PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks) Project. PERSIANN is an ongoing precipitation estimation project that began in 1995 and has expanded from small study areas to operational global coverage. His role is to handle the entire process for operational versions of the model and input data (IR, radar, microwave, gauge) and data visualization for the research versions.

Dan's expertise employed to facilitate all aspects of coding and operational data handling, data visualization, dissemination for the data produced by CHRS. Other data products have followed, PERSIANN-CCS and PERSIANN-CDR which have proven to be of major importance in the fields of hydrology and climatology. Other work includes collaboration with NASA on IMERG and GPCP v3.

Dan also handles the system adminsitration role for CHRS including server installation and maintainence, backups, web servers, and data archiving.
