ARW SINGLE OBSERVATION TEST W/ GLOBAL BE

Introduction

This exercise consists of running the GSI analysis with a single pseudo observation at a specified location, to illustrate how that observation influences the analysis. 

Further information on setting up a single observation test is available in section 4.2 of the GSI User's Guide. 

The ARW background field is provided in netcdf format, and the global BE is employed as the background error covariance.
