 # Introduction
 
-Welcome to Quantitative Environmental Sciences, a new course offered at 1B in Natural Sciences.
+**Welcome to Quantitative Environmental Sciences!**
 
 Quantitative Environmental Sciences (QES) is a multidisciplinary course designed to integrate the physics, maths, biology, and chemistry behind environmental issues and models of environmental systems.
 Students will explore how Natural Sciences will be instrumental in solving the real-world problems that we are currently facing and will continue to face in the coming decades.

 # Surface water and Flooding
 
-Flooding and impact of climate change
-
 In this series of lectures we will develop a series of models for the dynamics of surface water and its drainage. We will explore a series of simple models to eludicate the controls on the capacity of the drainage system ;  in cases where this is exceeded floods develop. There are a series of different types of flooding, ranging from fluvial flooding from rivers, pluvial flooding over the land, and then coastal flooding associated with sea level rise and storm surge. A different form of flooding arises from dam failure and release of fluids from a reservoir. The simplified models we will develop are based on models of fluid flow in channels, over and through the ground, and in river systems; we also develop models for flooding through urban areas, where there may be very large resistance to the flow, and rapidly evolving flow paths as debris is carried downstream.

 # Air Pollution and Atmospheric Chemistry
 
-__Lecture 18 – An overview of the atmosphere__
+In this part of the course we will consider the characterstics of atmosphere, air pollution, and their interactions with climate. It begins with an overview of the atmosphere’s structure, temperature variations, and the roles of ozone and radiatively active gases. Air pollution is then explored, focusing on key pollutants like nitrogen dioxide (NO₂) and particulate matter (PM), their sources, and historical trends. The course delves into the atmospheric chemistry of pollutants, explaining their removal through processes like gas-phase oxidation and photolysis, and calculating pollutant lifetimes. Aerosols, including their formation, composition, and role in heterogeneous reactions, are examined next. Finally, the relationship between air pollution and climate is explored, particularly how aerosols influence cloud formation, cloud properties, and climate through mechanisms like the Koehler theory.

 # Terrestrial Carbon
 
-Over the course of the next four lectures we will discuss the role of the land surface in Earth’s climate system. Although the land surface is not included in your climate model for the lab report, the land plays a critical role in Earth’s climate, both because it stores a lot of carbon (2-3x as much as the surface ocean) and because it is critical for Earth’s heat and moisture balance. The land surface is also critical for the production of trace atmospheric gases, which we learned at the end of Michaelmas term are precursors to aerosol formation. And the land surface is where the vast majority of methane that reaches the atmosphere comes from.
