[EnergyPlus_Support] When Weather Data isn't Available on the EnergyPlus web site


Over the last few years, a number of users have needed
weather data to use with EnergyPlus where we don't have
measured data (on the EnergyPlus web site). When possible,
we have created weather data using the Meteonorm software.
Meteonorm extrapolates hourly data from statistical data
for a location. Where statistical data aren't available,
Meteonorm interpolates from other nearby sites. Generally
a statistical approach is a last resort--weather files
generated from statistics will not demonstrate the normal
hour-to-hour and day-to-day variability seen in measured data.

Having stated all those warnings, we have just posted the weather
files that we have generated from Meteonorm on the EnergyPlus
Support YahooGroups web page
(http://groups.yahoo.com/group/EnergyPlus_Support/files/Meteonorm_Weather_Files/
 ).


Each .ZIP includes a .STAT (EnergyPlus weather data statistics),
.EPW (EnergyPlus weather file), and .INFO (Information about
the source data and limitations from Meteonorm).

IN ALL CASES, YOU SHOULD REVIEW THE .STAT FILE FOR THE LOCATION
BEFORE USING ANY OF THESE FILES TO ENSURE THAT IT REPRESENTS
THE CLIMATE OF THE LOCATION AS YOU UNDERSTAND IT. IN MANY CASES,
A NEARBY LOCATION WITH MEASURED DATA WILL BE MORE APPROPRIATE THAN
ONE DERIVED FROM STATISTICS. USE THESE FILES AT YOUR OWN RISK.

The following locations are now available:

   BRA_Rio.de.Janeiro_MN5
   ETH_Addis.Ababa_MN5
   HKG_Hong.Kong_MN5
   HRV_Zagreb-Pleso_MN5
   IRQ_Baghdad_MN5
   IRQ_Basra_MN5
   IRQ_Mosul_MN5
   MEX_Monterrey.Ciudad_MN5
   MEX_Monterrey.International.Airport_MN5
   MLI_Bamako-Senou_MN5
   NPL_Kathmandu_MN5
   PAK_Hyderabad_MN5
   PRT_Lisbon-Gago.Coutinh_MN5
   PRT_Lisbon-Portela_MN5
   SLE_Freetown_MN5
   USA_NM_Santa.Fe_MN5
   YUG_Novi.Sad_MN5

Please note... Meteotest significantly updated the wind and
other calculations [hourly wind direction in TMY2 (which we
use) was constant... the update makes them variable].
If you received a file from the team before early December 2004,
we strongly recommend that you download the new file.

We are working on getting data for another 200 locations
over the next few months--targets include Italy (60+ files),
Brazil, Ghana, Kenya, Ethiopia, Nepal, Bangladesh, and China.
All except Italy are from the UNEP SWERA project (so we're
waiting on the data to become available on the SWERA web site--
swera.unep.net/swera/).

As always, if you know of sources of weather data that
we might be able to share with the EnergyPlus community,
please contact us.
