11	tauu	Surface Downward Eastward Wind Stress	TAUX	tauu = -TAUX	yes	J.Zhang	Note, I was analyzing this variable from e3sm output. It turns out that TAUX(Y) is surface stress, which is in opposite direction to tauu(v) (wind stress). This was not caught in CAM's conversion table.
12	tauv	Surface Downward Northward Wind Stress	TAUY	tauv =- TAUY	yes	J.Zhang	Same as above

20	cl	Percentage Cloud Cover	CLOUD	cl = CLOUD *100.0		Chris Golaz	on model levels
21	cli	Mass Fraction of Cloud Ice	CLDICE	cli = CLDICE		Kai Zhang	on model levels For consistency with clivi, don't include snow in cli.
22	clivi	Ice Water Path	TGCLDIWP	clivi = TGCLDIWP		Kai Zhang	TGCLDIWP doesn't include snow water path.
23	clw	Mass Fraction of Cloud Liquid Water	CLDLIQ	clw = CLDLIQ		Kai Zhang	on model levels For consistency with clwvi, don't include rain in clw.
24	clwvi	Condensed Water Path	TGCLDCWP	clwvi = TGCLDCWP		Kai Zhang	TGCLDCWP doesn't include rain and snow water path.
25	hur	Relative Humidity	RELHUM	hur = RELUM		Chris Golaz	interpolated to 19 pressure levels
26	~~hurs~~	~~Near-Surface Relative Humidity~~	~~RHREFHT~~	~~hurs = RHREFHT~~
27	hus	Specific Humidity	Q	hus = Q		Chris Golaz	interpolated to 19 pressure levels
28	mc	~~Convective Mass Flux~~
29	o3	Mole Fraction of O3	O3	o3 = O3	Need input from Philip Cameron-Smith (Unlicensed)		interpolated to 19 pressure levels
30	pfull	Pressure at Model Full-Levels	P0, PS, hyam, hybm	pfull = P0hyam + PShybm		Chris Golaz

34	rlut	TOA Outgoing Longwave Radiation	FSNTOA, FSNT, FLNT	rlut = FSNTOA - FSNT + FLNT		Chris Golaz	Equation originally from NCAR. Using this ensures that individual TOA terms (SW, LW, up/down) are consistent with TOM net flux (rtmt): rtmt = rsdt - rsut - rlut
35	rlutcs	TOA Outgoing Clear-Sky Longwave Radiation	FLUTC	rlutcs = FLUTC		Chris Golaz	Slight approximation here since we are using TOM, but NCAR does the same.
36	rsdscs	Surface Downwelling Clear-Sky Shortwave Radiation	FSDSC	rsdscs = FSDSC		Chris Golaz
37	rsdt	TOA Incident Shortwave Radiation	SOLIN	rsdt = SOLIN		Chris Golaz

43	tasmax	Daily Maximum Near-Surface Air Temperature	TREFHTMX				We cannot use monthly h0 output for this. But the necessary data is in daily h1 files. We would have to create time series of monthly averages from these daily files.
