ThermoStat 3.1 - NEW 2014

Analyzing stream temperature data can be a challenging and arduous task. Biologists spend long hours using various data reduction techniques to characterize thermal regimes of streams. This laborious process is often fraught with spreadsheet date-time interpretation issues and much potential for human error. Analyzing large numbers of sites and and/or many years of data can be tedious and frustrating. 

We have developed a software program called ThermoStat, third version in 2012, designed to facilitate the processing and analysis of sub-hourly stream temperature time series. Useful features include an intuitive graphical user interface, pre-processing and aggregation of multiple input text files, time within optimal ranges and time above upper lethal thresholds for 80+ common fish species, as well as a variety of daily, monthly, weekly, seasonal and annual temperature statistics. 

ThermoStat can be used to describe a thermal regime in a variety of ways that incorporate measures of timing, magnitude, variability, duration, rate of change, and species specific temperatures. ThermoStat does not perform statistical tests or generate p-values. Output from ThermoStat can be used in statistical tests to examine trends through time, before-after, or control-impact experimental designs. 

ThermoStat will calculate measures even if you feed it an insufficient quantity or quality of data (e.g., missing data, poor data). It is the responsibility of the user to know the limitations of their input data and make appropriate judgment calls on the quality of the resulting output.

New in ThermoStat 3.1

-Added the ability to load legacy ThermoStat2 processed files for improved backward compatibility.
-The time series trimming process has been improved.
-Fixed a bug that prevented users from loading alternate time-stamp formatted files. ThermoStat V3


ThermoStat v3.0

-Adjusted the size of the program window to work with wide screen displays of resolution 1440 x 900 or higher (4:3 ratio screens of 1280 x 768 or higher remain compatible with this new design). 
-Added several new analysis algorithms including timing, magnitude and variability of annual and daily minima and maxima. And, analysis of daily maximum warming/cooling rates-of-change. 
-Added the ability to load a variety of input time-stamp formats. 
-Added input data gap checking and correction (insert null records) plus duplicate/reversed timestamp checking and correction (condense and/or insert null records). 
-Fixed seasonal analysis issues when the winter season starts before January 1st. 
-The 10% missing data threshold for excluding periods from analysis has been removed (i.e. results are reported regardless of how much data is missing from a period. Sample size (n) is reported for each period. 
-Fixed issues merging multiple time series that included leap years. 
-Fixed issues merging multiple time series that overlapped. 
-The Day-of-Year calculator now works in both directions (i.e.Date to DOY and DOY to Date). 
-Multiple user interface tweaks to provide an enhanced user experience. 
-Added new data processing procedures to facilitate building a temperature db from logger data text files. 
-Improved text file output formatting and automated Adobe PDF report generator.
