public class DiurnalSineWeatherTransformer
extends net.simplace.sim.io.resources.FWSimResourceTransformer
Transforms daily radiation and temperature to diurnal values using
sine curves.
WIKI_START
Temperature follows a sine curve during daylight and an exponential decay curve
during night between minimum and maximum temperature.
Radiation follows one of the curves specified by the user
- `Sine` - a simple sine curve ,
- `SinBeta` - sine of solar elevation (shifted sine curve)
- `SinBetaEffective` - as `SinBeta`, but corrected for lower atmospheric transmission at lower solar elevation.
as defined by (G).
== Input variables ==
- The field names (column names) of date, radiation, min and max temperature in the resource (CHAR)
- The number of steps the diurnal values are calculated (default is 24, i.e. hourly values) (INT)
- Latitude of the location (DOUBLE)
- The offset from noon of max temp `MaxTempTimeOffset` (default 1.5, i.e. max temperature occurs at 1:30 pm) (DOUBLE)
- The nocturnal time coefficient for temperature `NocturnalTimeCoefficient` (default is 4 hours) (DOUBLE)
- The radiation curve that should be used - one of `Sine`, `SinBeta` or `SinBetaEffective` (CHAR)
== Output variables ==
Output variables in the following order
- Key column(s) of the original resource (including date) in the same order and same datatype
- Time - Array of time for each step (h) (INTARRAY)
- Temperature - Array of Temperature for each step (°C) (DOUBLEARRAY)
- Radiation intensity - Array of radiation intensity for each time step (J m^-2 h^-1, kJ m^-2 h^-1 or MJ m^-2 h^-1) (DOUBLEARRAY)
- Radiation - Array of radiation accumulated between two time steps (DOUBLEARRAY)
- DOY - day of year (d) (INT)
- Daylength - (h) (DOUBLE)
- Daily total radiation - (J m^-2, kJ m^-2 or MJ m^-2) (DOUBLE)
=== Example ===
First we need a resource with daily weather, including min and max temp and radiation.

The transformer needs the resource id in it's `resource` attribute. Output variables
in the header section start with the resources key variables, followed by calculated
variables. The inputs for `DateField`, `!MinTempField`, `MaxTempField` and `RadiationField`
contain the names of the columns as defined in the resource above.

== Temperature ==
Temperature is calculated according to (G) eq. 3.9 for daytime
WIKI_END
\(12-d/2 Ungültige Eingabe: "<" t_h Ungültige Eingabe: "<" 12+d/2\):
\[
T_a(t_h) =T_{min} + (T_{max} - T_{min})\sin(\pi \frac{t_h - 12 + \frac{d}{2}}{d + 2p})
\]
WIKI_START
and (G) eq. 3.10 for nighttime
WIKI_END
\(t_h \leq 12-d/2 \quad\text{or}\quad 12+d/2 \leq t_h\):
\[
T_a(t_h) = \frac{T_{min}-T_{sset} e^{-\frac{n}{TC}} + (T_{sset}-T_{min})e^{-\frac{t_h - t_{sset}}{TC}}}{1-e^{-\frac{n}{TC}}}
\]
where \(T_a\) is the air temperature at hour \(t_h\), \(d, n\) are day- and nightlength, \(p\) is the offset from noon of max temperature and \(TC\) the
nocturnal time coefficient. \(T_{sset}, t_{sset}\) are temperature and time at sunsset.
WIKI_START
== Radiation ==
If `RadiationCurve` has the value 'Sine', then the radiation intensitiy follows the curve
WIKI_END
\[
I(t) \propto s(t) = \sin(\frac{\pi}{d} (t - (12-\frac{d}{2})))
\]
WIKI_START
If it has the value `SinBeta` the curve (G), eq. 3.2 is used:
WIKI_END
\[
I(t) \propto sin\beta(t) = a + b\cos(2\pi \frac{t - 12}{24})
\]
where parameters \(a,b\) depend on latitude and daylength.
Diurnal Radiation at a timestep \(t_i\) is the radiation accumulated between the previous
and actual timestep.
\[
R(t_i) = \int_{t_{i-1}}^{t_i}I(t)dt
\]
