An Investigation of Data and Analysis Error on February 21 1977

"Last year a test was conducted at the National Meteorological Center (NMC) to choose a successor to the then operational 6-layer Hemispheric Primitive Equation Prediction Model (Shuman and Hovermale, 1968)--hereafter referred to as the 6L PE. Three different models were contenders for the role of successor: a model similar to the 6L PE but with half the grid size (HFM), a nested grid model (NGM), and a 9-layer hemispheric version of the NMC 2.5° Global Model (NLH) (Stackpole, Vanderman, and Shuman, 1974)"--Introduction.
