+This repository provides a set of notebooks to pedagogically introduce the reader to the problem of parameterization in the climate sciences and how machine learning may be used to address it.
+
+The original goal for these notebooks in this Jupyter book was for our [M2LInES](https://m2lines.github.io/) team to work together and learn from each other; in particular, to get up to speed on the key scientific aspects of our collaboration (parameterizations, machine learning, data assimilation, uncertainty quantification) and to develop new ideas. Now this material is presented here for anyone to learn from. The primary audience for this guide is researchers and students trained in climate science wanting to be introduced to machine learning or trained in machine learning and want to get acquainted with the parameterization problem in climate sciences. Since the book addresses people from multiple fields the level of pre-requisites required is minimal; a basic understanding of Python and some experience with PDEs or dynamical systems and solving them numerically (an introductory course in numerical methods) can be helpful. This book could be used as a teaching tool, for self-study, or as a reference manual.

+Most readers interested in learning from this material could just run individual notebooks once they have setup the appropriate environment, or use the binder link provided at the top of this readme. However, some more advanced readers, particularly those wishing to contribute back, may be interested in building the book locally for testing purposes.

 The book was created by and as part of M2LInES, an international collaboration supported by Schmidt Futures, to improve climate models with scientific machine learning. The original goal for these notebooks in this Jupyter book was for our team to work together and learn from each other; in particular, to get up to speed on the key scientific aspects of our collaboration (parameterizations, machine learning, data assimilation, uncertainty quantification) and to develop new ideas. This was done as a series of tutorials, each of which was led by a few team members and occurred with a frequency of roughly once every 2 weeks for about 6-7 months. This Jupyter book is a collection of the notebooks used during these tutorials, which have only slightly been edited for continuity and clarity. Ultimately, we are happy to share these resources with the scientific community to introduce our research ideas and foster the use of machine learning techniques for tackling climate science problems.
 
+# Statement of Need
+Parameterization of sub-grid processes is a major challenge in climate modeling. The details of this problem may often be very context dependent (@christensen2022parametrization), but much can be learned by addressing the issue in a general and simpler sense. Also, a general approach allows non-domain experts, e.g. machine learning researchers, to engage and contribute more meaningfully. This JupyterBook aims to achieve this target with the help of a simple dynamical system model - Lorenz 96, such that the reader is introduced to the basic concepts with minimal superfluous complexity. It is possible to extend the concepts that are presented here to other dynamical systems, and even to more complex parameterization tasks (some examples can be found at https://m2lines.github.io/publications/), and we hope that researchers and learners aiming to do this find the concepts presented here as a useful stepping stone in this pursuit.
+
+As described above, these notebooks were originally created to introduce non-domain experts to ideas from the parameterization aspects of climate modeling and how machine learning could be used to potentially address these. Now they have been adapted to act as a pedagogical tool for self-learning, be used as a reference manual, or for teaching some modules in an introductory class on machine learning.
+The book is organized in sections that are relatively independent; with the exception that the first section provides a general overview to the parameterization problem in climate models.
+Each notebook covers material that can be discussed in roughly an hour-long lecture, and sections can be mixed and matched or ordered as needed depending on the overall learning objectives.
