ARCHIVE REDONE
The archive process may have failed this morning,
so I am rerunning it. There was no printed output
and the tape was ejected from the exabyte drive.
There was also a mail message (which I have lost)
from crontab indicating some problem with the
archive of the files in the inter directory.
The second archive was successful.

PROGRAM USE TO CALCULATE SURFACE HEAT FLUX TO BE USED FOR STORMFEST
THIS PROGRAM IS TO CALCULATE THE SURFACE HEAT FLUX, G, FROM THE
8cm HEAT FLUX, G8, AND THE SOIL TEMPERATURES AT 1cm, 3cm, 5cm, AND 7cm
The relationship used to relate the measured soil heat flux determined at 8cm
to the heat flux at the very surface is:
Gi = G8i +(Csoil * 0.08 * (Tsoil(i+1) - (Tsoil(i-1)) / (t(i+1) - t(i-1))
where: Gi is the surface heat flux at time i
G8i is the 8cm heat flux at time i
Csoil is the heat capacity of the soil
Tsoil(i-1) is the weighted mean temperature of the top 8 cm
of soil at time i-1
Tsoil(i+1) is the weighted mean temperature of the top 8 cm
of soil at time i+1
Tsoil(i+1) = (T1cm(i+1) + 3*T3cm(i+1) + 3*T5cm(i+1) + T7cm(i+1))/8
Tsoil(i-1) = (T1cm(i-1) + 3*T3cm(i-1) + 3*T5cm(i-1) + T7cm(i-1))/8
i+1 refers to the data recorded at t(i+1) seconds
i-1 refers to the data recorded at t(i-1) seconds
(t(i+1) - t(i-1)) is twice the time interval = 2 * 5min = 600s
Csoil = (1.05 + (6.09 * gravmoist)) * 10**6
# The values for the coefficients were derived from estimates of the soil propertites
# at the Sebetha site. They were provided by Jay Ham, KSU.
# Bulk density = 1.45 g cm-3
# Mineral particle density = 2.65 g cm-3
# Organic material density = 1.00 g cm-3
# Water density = 1.00 g cm-3
# Volumetric mineral fraction = 0.55
# Volumetric organic fraction = 0.01
# Volumetric water fraction = 1.45/1.00 * gravmoist
# Csoil = (1.9*volumetricminfract + 2.5*volumetricorgfract + 4.2*volumetricwaterfract)
# = (1.9*0.55 + 2.5*0.01 + 4.2*1.45*gravmoist)
# = (1.05 + 0.025 ) + 6.09 * gravmoist
# = ( 1.08 + 6.09 * gravmoist)
G should be calculated for each of the three locations, furrow, intermediate,
and ridge.
Furrow: Gfur corresponds to G1.8cm, T1.soil, and T1.index
Intermediate: Gint corresponds to G2.8cm, T2.soil, and T2.index
Ridge: Grid corresponds to G3.8cm, T3.soil, and T3.index
Finally a mean G should be calculated for the surface>
G = (Grid + Gint + Gfur)
NOTE ADDED 21 APRIL 1992
In the field five dirt clod were collected trimmed to a regular
shape and dried in the oven to constant weight. They were then wax impregnated
using parawax and a heat gun. They were returned to the lab and on 20 April
their bulk densities determined using the recorded mass and the volume
determined by immersion in water contained in a graduated beaker.
The accuracy of the volume determination was only +/- 5 cm3.

NOTE ADDED 29 JAN 1993
Samples of the top 8cm of soil had been collected at the site and
stored in plastic containers in the lab. In order to determine
mineral particle density a portion of the soil was oven dried at 110 C
and then three aliquots of ~20.0 cm3 were first weighed dry and then
saturated with water.
Sample C' was done 29 Jan, the others on 5 Feb

The following relationships were applied:

watervolfrac* = (pore.water/volume) * waterdensity
= ((sat.mass - drymass)/volume) * 1.0
minvolfrac = 1 - watervolfrac*

NB bulkdensity* is not the true bulkdensity = blkdens obtained
from the measurement of soil clods. bulkdensity* is the effective
density of the dried sieved soil which is processed to determine the
mineral grain density.
Likewise watervolfrac* is also a parameter used solely for this purpose.
A value of mindens and of minvolfrac were calculated from the mean of the
above, ignoring Sample A
Mindens = 2.17 +_ 0.09 g cm-3
Minvolfrac = 0.47 +_ 0.01
Bulk density = 1.38 +_ 0.16 g cm-3
An upgrade can be made to the previous estimate of Csoil
# The values for the coefficients were derived from the soil properties
# of samples taken at the Sebetha site and analysed in the lab.
# Bulk density = 1.38 g cm-3
# Mineral particle density = 2.17 g cm-3
# Organic material density = 1.00 g cm-3
# Water density = 1.00 g cm-3
# Volumetric mineral fraction = 0.47
