Turbine Inflow Turbulence ANalysIs Code

What is TITANIC?

TITANIC stands for Turbine Inflow Turbulence ANalysIs Code. This code is designed to analyze data obtained by a research-grade met tower with a focus on providing the data needed for wind energy applications, also known as turbine inflow.

TITANIC can:

• Read in raw data from a meteorological tower
• Apply calibrations or remove data known to be bad
• Carry out basic quality control
• Analyze data to quantify the conditions that are being measured by the tower
• Produce statistics and data about those conditions, including
• mean wind parameters, like speed and direction, shear, and veer.
• turbulence parameters, such as turbulence intensity, dissipation rates, and structure functions.
• thermodynamics parameters, such as virtual potential temperature, monin-obukhov length, and Richardson number.
• Create plots and web pages for each data file
• Push data to an archive

See How Does TITANIC Fit in a Data Processing Workflow for details.

Where is TITANIC used?

TITANIC is used by the National Renewable Energy Laboratory to analyze data from the National Wind Technology Center's M4 and M5 135-m towers. Find out more at https://nwtc.nrel.gov/MetData, and see the most recent data at https://nwtc.nrel.gov/M5. All plots were produced by TITANIC.

What do I Need to Use TITANIC?

1. MATLAB.
2. Sense of humor.

titanic's Issues

Error running TowerRunAnalysis.m

Dear all,

I was trying to run TowerRunAnalysis.m but I faced the following error:

Warning: Problem running TowerRunAnalysis.m generated by TowerRunAnalysis:Run.
Error: Error using TowerRunAnalysis (line 145)
Problem running FirstLook.m generated by tower_main:Run.

Please, can anyone help me in this issue?

Best regards,
Jonathan

missing QCReports folder

To run TowerRunAnalysis.m, user should not have to first create their own 'log_path' folder.
'local/MetData/M5Twr/QCReports' should already exist

Redefine how precipitation information is handled

At the moment TITANIC assumes that the precipitation sensor returns data in the range 0-3, where anything less than 3 indicates some precipitation.

This should probably be adjusted so that precipitation is in the range 0-10, where 10 corresponds to the highest measurable intensity, and 0 is no observed precipitation. This may require some instrument-specific code.

A structure, tower.precipsensor, exists. This currently contains the channel number of the sensor. This structure could be expanded to include more information about the sensor.

default date range does not span included data

In AdminCodeTester.m, all 'from_date' and 'to_date' should be changed to span July 29, 2015, the included example data.

Suppress Figures

In some cases, TITANIC generates a huge number of plots. Can we suppress those figures?
