Simulated One Point Mode

This mode is currently only supported for Mars.

It requires:

1: a Temperature T

2: @ a season ls

3: @ a LTST hour

 OUT = krc(lat = 12., lon = 12., T = 190., ls = 0., hour = 4.)

The output is the equivalent thermal inertia in J m-2 K-1 s-1/2, in this case OUT = 334 Jm-2K-1s-1/2.

The One-Point Mode outputs a TI (SI) for an array of input temperatures with the given parameters

It can output various values that indicate why a TI was not derived for failure cases:

-600: The Temperature provided is lower than the lowest model output. Possible Frost Presence

-500: No value was derived or returned. KRC may have failed to run all together

-400: Negative TI value. This is a non-physical return as a function of the fitting routine

-300: TI value larger than 2200 SI. 2200 SI is the top of the available lookup table and extrapolation is not permitted

-200: Returned TI value doesn't meet proximity criterion (TI_Guess_PCT)

-100: Bad TI_Guess / TI_Guess_PCT combination. This is most likely a user error

SOMETHING ABOUT TI_Guess_PCT and TI_Guess

Validity not met => -200.

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=300.,TI_Guess_PCT=0.05)

Validity met => 334.

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=300.,TI_Guess_PCT=0.2)

No validity criterion specified, good guess => 334.

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=300.)

No validity criterion specified, poor guess => 641. You shoot yourself in the foot

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=900.)

No guess, slow, => 334.

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.)

Pathological Case; KRC runs, sets TI_Guess to 0., and returns a flag => -100.

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess_PCT=0.2)

Below Frost point => -600. (The solution was a negative TI)

OUT = krc(T=130,ls=0.,hour=4.,lat=12.,lon=12.)

Below Frost point, horrible guess but -600

OUT = krc(T=130,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.)

Below Frost point, horrible guess -200

OUT = krc(T=130,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.,TI_Guess_PCT=0.5)

Much too warm => flags high TI => -300.

OUT = krc(T=500,ls=0.,hour=4.,lat=12.,lon=12.)

Much too warm, poor guess => flags high TI => -300.

OUT = krc(T=500,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.)

Much too warm, poor guess => flags poor guess => -200.

OUT = krc(T=500,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.,TI_Guess_PCT=0.1)

No guess, slow, => 334.

OUT = krc(T=190,ls=000.00,hour=4.,lat=12.,lon=12.)

No guess, slow, => 334.

OUT = krc(T=190,ls=359.99,hour=4.,lat=12.,lon=12.)

Sets DELLS=0. to avoid this issue but error message: Please do not set both DELLS and DELJUL XXX

OUT = krc(T=190,ls=359.99,hour=4.,lat=12.,lon=12.,DELLS=0.)
