Visualizing DBT and RH in Ahmedabad. Part 1

Submitted by Anonymous (not verified) on October 15, 2012 - 12:40pm

This series of posts explores different ways of visualizing the Dry Bulb Temperature (DBT) and Relative Humidity (RH) for a typical year using TMY2 (check) data. These are executed in R (link). It can serve as a template to visualize other time series data.

Once this series is over, I intend to focus on visualizing cyclical data. More on that later

"Truth" is really nothing more than a "correspondence" with the facts, and an important role for the econometrics is to articulate what constitutes a satisfactory degree of correspondence
~Poirier (1988)

Essentially, all models are wrong, but some are useful.
