Dr Viju Oommen John
Viju is a climate scientist working on creating homogenised radiance data sets from microwave and infrared satellite measurements for climate monitoring and evaluation of climate models.
Areas of expertise:
Satellite remote sensing.
Upper tropospheric humidity.
Evaluation of climate models using satellite observations.
Viju mainly works with microwave and infrared satellite measurements of tropospheric temperature and humidity with the aim of understanding clear-sky long wave feedbacks in the climate system. Climate model simulations are also used to understand this better.
Viju is currently on secondment at EUMETSAT.
Viju joined the Met Office Hadley Centre in 2008. Prior to that, he did a postdoc with Prof. Brian Soden at the University of Miami (2006-2007) on evaluating climate models with satellite observations and a PhD with Prof Stefan Buehler at the University of Bremen, Germany (2001-2005) on creating and analysing upper tropospheric humidity data sets from remote sensing and in situ measurements. Viju did his postgraduate studies in India; M. Sc. in Physics and M. Tech in Atmospheric Sciences, both from the Cochin University of science and Technology, Cochin, India.
