Split off Chapter 3.3 and 3.4

Split off these two sections as they constitute to potentially a
separate chapter. Also to make the .tex more manageable.
Tracer Correlation

First part of tracer correlation: O3-CO correlation + figure
Tracer maps

Raw passive tracer analytics for lateral, BL, strat, and lightning
tracers.
Included full figure for x-y@300hPa and y-p@33N
Wrap up tracer relation

Wrapping up sect 3.3.1 on tracer relation
Added figures on age map and passive tracer correlations
Added labels and annotations to tracer maps
Tendency time series

Included figure and extensive discussions
Updated species availabilities in Sect 3.1
Tendency vertical profiles

Added discussion of tendency vertical profiles for ozone and a 3-panel
figure for Trinidad Head, Houston, and Beltsville.
Chemical pathways

Subsubsection on chemical pathways analyzed through chemical tendencies.
Included figure and table illustrating "chemical EKMA" (internal name)
Chemical pathways (edits)

Edits to chemical pathways subsection + figure and paragraph on
advective tendency residuals. Included backup figure on CO-NOx EKMA
Section 3.4 lightning

Lightning sensitivity map for O3, CO, NOx, HOx
Lightning sensitivity distributions

Added paragraphs and figures discussing the changes in O3,Ox, CO
chemical tendency in relation to lightning emission
Lightning sens chem and conv

Added the followings:
1. LN/Q Kleinman 2001 analytics
2. Convective tendency sensitivity to lightning
3. Related figures
Anthrop/biog. sensitivity

"Sensitivity" simulations for anthropogenic and biogenic emissions.
Added figures, not using biosens (map mosaic) for now.
removed EKMA

Removed section about chemical EKMA
Chapter 3.3/3.4 proofread

Pre-iteration 1 proofread for second half of chapter 3
Conclusion

Summary for the entire chapter (2 pages)
Section 3.3.1 it 1 mcb

Iteration 1 edit according to recommendation by Mary Barth.
Replaced both contoured figures with larger fonts and "rainhow"
palettes.
Masked out tracer age map

Masked out low variance data points from map defined where tracer value
< 1e-4.
Updated figure caption to reflect changes to colorscale and masking.
Iteration 1 edit dcn

First iteration edits based on recommendations from David Noone.
Updated figure labeling
Sect 3.3/4 it 1 edit mcb

Iteration 1 edit for sections 3.3 and 3.4 according to recommendations
by Mary Barth
Merge branch 'Chapter-3.5' into Chapter-3
