Anomaly Correlation Statistics Change Details

29-Sept-2017 (beta and production)

• Cleaned up the header line to reflect the actual levels returned by the query. So, when the user asks, e.g., for 100-1000mb for HGT (which is only defined at 500 mb), he or she will see '500mb' as the indicated level in the header.
• Also, made the model name editable so you don't have to scroll down through the long list.
• Also updated GSD.AC_stats.jnlp so it (1) won't be cached, and (2) defaults to a 5-day time window. (The previous 1-month time window led to very long queries.)
• (Routines changed: getStats.cgi, StatsDisplay, DisplayFrame, CurveParameters.)

28-Aug-2016 (beta and production)

New out-of-browser version of the java display (GSD.AC_stats.jnlp) is now available and linked from the display. Even in browsers that don't run java applets, the link to this file below the (possibly absent) java applet allows the display to be run outside of your browser. Depending on your operating system, you may need to download this file and then click (or double-click) it to run it. On macs, you may need to right-click on the downloaded file to force it to run even though it's from an "unidentified developer".
(Routine StatsDisplay was upgraded to set the default time window to the past month whenever optional date parameters (available in the browser-based display) are not present.)

25-May-2016 (production)

All beta changes moved to production

3-May-2016 (beta)

Added the number of runs to the text output, and removed the misleading statistical summary in the text output for the dieoff curves.

5-Oct-2015 (beta)

Background lines are now light gray; sig digits on the ordinate default to 1; time axis shows 4 digit years, legend text can now be changed by clicking on the legend; x and y axes can be changed by double-clicking on them. Routine(s) changed: DisplayFrame. (Also, gov.noaa.pmel.sgt.SGLabel changed to default to Color.black if no color is specified--but this didn't change the behavior of this particular applet.

8-Sept-2015 (production and beta)

'Plot Pairwise' option corrected. It accidently always compared each curve with the first. Routine(s) changed: getStats.cgi

11-May-2015 (production)

All beta changes moved to production.

7-May-2015 (beta)

We now use 'reasonable' values when the axes are scaled and rescaled. Also, increased the widening of error boxes with each different curve so they're easier to distinguish. Routine(s) changed: DisplayFrame.java (uses calls to gov.noaa.pmel.sgt.Graph.computeRange).

23-March-2015 (production)

All beta changes moved to production

7-Feb-2015 (beta)

• Added 'Dieoff' as a 'fcst' option to generate dieoff plots with the same code as time series plots.
• In the db query, we now use MySQL's 'group_concat' function to return all the samples (valid times) within a grouped query. We use these to generate the std error for the samples within the group. Routine(s) changed: getStats.cgi, gov.noaa.fsl.frd.lib.ErrorProcessor (new).
• Subroutine 'query_and_fill' created to simplify(?) query generation, in hopes of code reuse. Routine(s) changed: getStats.cgi.
• Java standard error calculation changed slightly to use the number of good samples (rather than the total number of samples) in converting from standard deviation to standard error. If there is no missing data, the std error is unchanged. Also, we now only calculate 1 lag, because that is all that is required. (Previous version calculated all lags. This was fast enough in java, but not in the perl cgi script. Routines changed: gov.noaa.fsl.frd.lib.Stat.
• Plot routine given major rewrite to avoid using the pregeneraged layout (JPlotLayout) to provide more control over plotted layers. (Thanks to Patrick Hoffman for paving the way for this.) We plot each curve and each set of error bars as separate layers. We also have the capability to include textual information near each data point. Routine(s) changed: DisplayFrame.

21-Jan-2015 (production)

All beta changes moved to production

5-Jan-2011 (beta)

The drop-down list for years now updates automatically to include the current year +1. Routine(s) changed: CurvesControl, lib.JYearBox.

2-Nov-2010 (beta)

Got rid of html text in buttons, because the latest update of java seems to not support them. Also, changed the default to not showing difference curves. Routines changed: CurvesControl.

5-Mar-2010 (beta)

• Dates default to the past 30 days (really).
• Difference curves are now optional
• Curves are plotted as lines without data points if more than 60% of the data are present. Otherwise, lines are plotted with data points.
• Standard error is calculated, and presented in the text window, even if there are missing data.
• Summary statistics for each curve are presented atop the text in the text window.
• (For internal use: "debug=true&" can now be added to the query string of getStats.cgi to provide debug information.)
• Routines changed: Welcome.cgi (was Welcome.html), getStats.cgi, DisplayFrame, SimpleLine2, CurvesControl, StatsDisplay.

3-Oct-2009 (beta)

Default dates now default to the past 30 days. Routines changed: CurvesControl, StatsDisplay.

22-Sep-2009 (beta)

Added the ability to select dates, and a text window that shows numerical values plus statistics for each curve. For curves with missing data, the mean, sd and number of points are shown; for curves with no missing data, the standard error, autocorrelation at lag 1, and the min and max are also shown. Routines changed: CurvesControl, DisplayFrame, StatsDisplay, getStats.cgi.

24-November-2008 (beta)

Added FIM430 to Welcome.html

12-November-2008 (beta)

Added FIM378L64-SHAL to Welcome.html

10-November-2008 (beta)

Added FIMretro-378L64 to model option

Changed "height" to "HGT" in CurveParameters.java

Changed getStats.cgi to look for "HGT" instead of "height"

Changed Welcome.html to use anom5.jar

20-October-2008 (beta)

Added FIMretro-378 to model option

Added UGRD and VGRD to variable option

??-October-2008 (beta)

Added 12,36,60,84,108,132,156 to projection

1-July-2008 (production and beta)

Fixed to allow time series for only 0Z or 12Z runs. Routines changed: getStats.cgi.

16-June-2008 (production and beta)

Implemented new regions, to be consistent with the model-RAOB database. Also added region names, rather then numbers, on the output plots. Routines changed: CurveParameters, DisplayFrame, getStats.cgi.

2-May-2008 (beta)

Started this, based on http://ruc.noaa.gov/stats/new/
