Neue Seite

= The *.TRY Format for Climate Data =


You can use existing TRY weather files (file format *.TRY) to perform WUFI
calculations; you can also convert your own weather data to that format
and use them.


This format was used by the German National Weather Service DWD for the test
reference years published in 1986 (the new test reference years, published in
2004, are in
[[TheDATFormatForClimateData.htm | *.DAT]] format). Also, this
format was used for some of the climate files
[[DialogClimateFileSelectMap.htm | supplied with WUFI]].


The 1986 test reference years (TRY) cannot be purchased from DWD any more
(they have been replaced by the 2004 test reference years), but existing
old TRY can still be used with WUFI. They contain synthetic hourly climate
data which - based on seasonal mean values and long-term annual mean values -
represent typical weather conditions for different geographical regions [1].


Please note that these (1986) test reference years may be of limited
usability for calculating the moisture balance of building components, since
they have been designed for thermal simulations only. The total amount of
precipitation is reproduced correctly, but the number of hours with precipitation
is overestimated [2]. With building materials of low absorptive capacity,
however, the duration of precipitation is more important than the
amount of precipitation.


WUFI can read two different variants of the TRY format: the IBP variant and
the DWD variant.


=== IBP variant ===

TRY weather files consist of 24 lines of header and 8760 lines of weather
data in hourly intervals.


Example:


<IMG SRC="pix/IBPTRYexample.gif" WIDTH="565" HEIGHT="572" VSPACE="0" HSPACE="0" ALT="">



WUFI skips the header, with the exception of lines 3 and 4, from which it
reads the geographical position of the measuring site.


Since the file format is a remnant from the FORTRAN era, the column-oriented
structure of the file has to be followed strictly. It is not necessary, however,
to stick to the exact floating point format of the numbers themselves: for
example, WUFI reads columns 42-47 as a <TT>string</TT> and then converts it to a
<TT>real</TT> number.


A TRY file contains 8760 data lines with hourly weather data. The first one
of these consists of the mean weather data for the hour from 0:00 to 1:00 CET
on January 1. There is no intercalary day (February 29).


The meaning of the weather data in detail:


<UL>
<LI>Column 1-5: site ID.
<DL><DD>Not used by WUFI.</DD></DL>
  
</LI>

<LI>Column 6-10: cloud cover (0..1).

<DL><DD>Not used by WUFI.</DD></DL>
  
</LI>

<LI>Column 20-24: wind velocity, vectorial mean [m/s].
<DL><DD>Since no wind direction distributions are provided in the
TRY files, this loss of information must be compensated by using
the vectorial mean instead of the scalar mean. 
  
The vectorial mean of the wind velocity is the mean value of the readings
of an anemometer with the directions taken into account. For example, if
for an hour the wind is blowing at 2 m/s but at the same time steadily
travelling through all the directions, then the vectorial mean is 0 m/s,
whereas the scalar mean is 2 m/s. 
  
In the vectorial mean, some vector components may cancel. Thus, the
vectorial mean is always less than (or at most equal to) the scalar mean. 
  
If only the mean direction and velocity are provided, no individual
treatment of specific directions is feasible anymore. Therefore, it is
not possible to disregard wind directions which hit the building component
from behind and thus don't contribute to the rain load. In a driving rain
situation, however, the wind will mostly blow from a narrow range of
directions, so that the mean direction will be reasonably representative.
</DD></DL>
  
</LI>

<LI>Column 25-27: DWD code for regular weather observations.
<DL><DD>Not used by WUFI.</DD></DL>
  

<LI>Column 28-34: precipitation during the last hour [mm].
<DL><DD>The rain load on a wall is determined by the driving rain
rather than the normal rain. If no measured data on the driving rain
are available, it can be estimated from other data. 
  
The rain coefficients R1 and R2 in the dialog
<A HREF="DialogEditSurfaceCoefficients.htm">"Edit Surface Coefficients"</A>
serve to estimate the driving rain load on a surface of arbitrary orientation
and inclination from data on normal rain, wind velocity and wind direction,
using the relation 
  
<CENTER>rain load = rain · (R1 + R2 · wind velocity),</CENTER>
  
where 'rain' is the normal rain and 'wind velocity' is that component of the
mean vectorial wind velocity (measured at a height of 10 m, in open area),
which is orthogonal to the building surface. 
  
R1 and R2 are strongly dependent on the specific location on the building
facade. If calculations are to be compared to actual measurements, these
coefficients should be experimentally determined for that location. 
  
If they cannot be measured, only a very rough estimate is possible. For
vertical surfaces, R1 is zero. R2 is about 0.2 s/m for free-standing locations
without influence from surrounding buildings etc.; it is markedly less in
the center of a facade (e.g. 0.07 s/m); it may even be greater at exposed
locations of a building (near edges and corners) [1].

<DL><DD>The direct component of the solar radiation (i.e. received

From this, the direct normal radiation can be calculated, i.e.,
the amount of radiation incident on a surface that is orthogonal to
the beam direction [3]. This calculation requires knowledge of the
time and geographical location of the measurement, since the corresponding
position of the sun has to be determined. 
&bnsp; 
The direct normal radiation can then be used to calculate the direct
radiation incident on a surface with arbitrary orientation and inclination.
Addition of the appropriate fraction of diffuse radiation results in the global
radiation incident on the building component. 
  
These calculations are automatically done by WUFI during a simulation run.
WUFI uses a simplified radiation model which treats the diffuse radiation
as isotropic and ignores the albedo of the ground. If you are more demanding
or want to allow for local specifics (like shadows etc.), you can
