WAsP Climate Analyst 3.0 Rel.F Build150

WAsP Climate Analyst (”WACA”) release notes


Version 3.00.150 (Release F)

A. Import reports extended to include all data import settings: Column description, discretization width, scaling factor and offset, calm threshold and min. and max. limits of the data window.
B. A bug regarding repeated time-interval setting for OMWCs and OEWCs has been fixed.
C. Automatic instrument identification (incl. height) from header-line labels has been improved. 
D. A bug re. abscissa-axis labels for OEWC and OEWC-Pot has been fixed.
E. An error in the OEWC-POT analysis warning texts has been corrected.
F. The help-article for OEWC-POT has been updated.


Version 3.00.146 (Release E)

A. Improved visibility to original file in file import by showing the header file and 10 first data lines in the file import dialog first page.
B. Updated POT- module with improved quality control.
C. Sample data improved.
D. Improved file format detection
E. Some minor GUI detail updates.


Version 3.00.136 (Release C)

A. Wrong data averaging period in exported wind time series files (.amos) fixed.
B. Certain typos in warning texts fixed.
C. Sample files installation made to comply with convention used by WAsP and WAsP Engineering.


Version (Release B)

A. File header lines viewer has been added.
A facility to view file header lines during data import has been added. This should clarify the identification of the various data items (time stamp, wind speed, wind direction, .. )

B. Data processing progress monitor improved.
The monitor showing the progress of user-specified data treatment and calms calculation has been improved.

C. Extreme wind climate scatter plot clarified.
The scatter plot displaying extreme wind data has been made more clear, now enhancing the points representing the largest wind speeds per year (OEWC) or per storm (OEWC-POT).

D. Bug in extreme wind climate sampling fixed.
A bug, which caused certain problematic years to be skipped totally, has been fixed. The problematic years were characterized by the high winds being concentrated in a small part of the year.



Version (Release A)

WACA 3.0 is a completely new WACA version. Some of the features from WACA 2.0 are still present, but there are a number of completely new features meant to make it much mOre intuitively easy and convenient to use.

  1. New Data import and automatic data format detection procedure.

In far the most cases the data format will be automatic detected: Time stamp, wind speed(s) and wind direction(s); wind speed and wind direction columns assignments may, if needed, be overwritten by the user.  

In case a data file contains a header line with column labels containing an instrument height – e.g. WS_45 or WD_30 – the corresponding data are automatically assigned to an “instrument” at the appropriate height. In case the instrument height could not be detected, the user may perform the correct assignment. 

So no protocol editor as in WACA 2!

  1. Time trimming

Trimming of the time range(s) to be used for the observed wind climate generation may now be specified at any time AFTER the data import (without having to re-import the appropriate data file(s)). It is simply specified via a special Time-selection page of the Observed Wind Climate in question (OMWC, OEWC or OEWC-Pot).      

  1. POT-extreme wind climate

In WACA 3.0 we offer, in addition to the Periodical-maxima Extreme wind analysis (OEWC) also the use of the well-known Peak-Over-Threshold extreme wind analysis method (OEWC-Pot). The next WAsP Engineering 3 version will be able to utilize OEWC-Pot.


How to use all the new features is well described in the HELP-system of the WACA3.0. Especially we recommend using the “Quick Start Tutorial”.
