Real-time Forecasting Methods Validation: Flare Scoreboard

CCMC is in the implementation phase of the "Flare Scoreboard" together with Sophie Murray of the UK Met Office and the international research community. The flare scoreboard is an automated system such that model/method developers upload their predictions automatically uploaded to an anonymous ftp which will be parsed by the system. The forecasts are shown on an interactive display of SDO/AIA or HMI images, and will also be displayed together on a graph of probability vs. time.

Proposed forecast submission file format and Registration Questions:

Flare scoreboard functions and workflow:
     Participants respond the questionnaire below to get started (see below).
     Participants produce probabilistic flare forecasts conforming to the file format (XML or plain text; see below). Additionally, occasional participants can provide forecasts by filling out a form, similar to the CME scoreboard. (Please contact Leila Mays if you would like to use this option).
     Flare forecast files are accepted by anonymous ftp, within the relevant subdirectory. Forecast files will be processed at least every hour.      The minimum requirement for participation is a probabilistic Full Disk Forecast for M and X bins. Active Region forecasts and C bins are also accepted.
     Required forecast information includes: Forecasting Method, Issue Time, Prediction Window Start/End Time, M and X flare Probability. For Active Region Forecasts, Region number, Location, and Time is also required. See below for details.
     All information is stored in a database and is made accessible to users. Click here to learn how to download flare forecast files from the database.
      CCMC Rules of the Road apply: CCMC requests that users notify the CCMC, flare model/technique developers and submitting forecasters before performing validation studies with the Flare Scoreboard database. It is recommended that such validation studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.
     Probabilistic forecasts are displayed side by side on the "Flare Scoreboard" website.

Proposed forecast submission file formats:
Flare forecasts will be accepted via three avenues (click each for proposed template):
    (1) XML: XML schema, , template, full example

File notes:
     Color coding: blue=optional, use four dashes if empty: ----.
     "Probability Bins" should be specified as "M" or "M+" depending on whether the method forecasts "M1.0-9.9" or "M and above"
     Probabilities and uncertainties should be displayed as decimal, not percent, up to four decimal places.
     Forecast files will be processed every six hours based on the forecast Issue Time of 0, 6, 12, and 18 UT. The files will be accepted within a file submission time cushion (±0.5h), such that event if the file is delayed, it is the forecast issuance time that is used.

Model/Technique Registration (*=required):
Information about your group/project:
    Name(s) and e-mail (s) (please list primary contact first)*:
    Associated Institution/Project name/Group name*:
    Website url(s):

Information about your method:
    Forecasting method name*:
    Shorthand unique identifier for your method (methodname_version, e.g. ASSA_1, ASAP_201201):
    Short description*:

Further Model Details:
    (1)* Please specify if the forecast is human generated, human generated but model-based, model-based, or other.

    (2)* Does your flare prediction method forecast “M1.0-9.9” or “M and above”? Would it be difficult for you to adapt your method from one to another? Which forecast binning method do you prefer?

    (3)* How do you specify active regions in your model? Do you relate their location to other schemes such as NOAA or Catania? If so, what is your criteria to relate them?

    (4)* Uncertainties given as an upper and lower bound is an optional field. Does your model provide uncertainties for the forecasted probability?
If yes, what percentiles do you use to determine your upper and lower bound? If you are using the XML format, multiple percentiles of the probability density distribution can be specified.

    (5)* For each forecast, what prediction window(s) does your method use? E.g. Does your method predict for the next 24 hours, 48, and 72 hours or the next 24 hours, 24-48 hours, 48-72 hours? (This information is useful for displaying only comparable methods together).

    (6)* For how many degrees from disk center is your full disk forecast valid for? E.g. 60 degrees; or 90 degrees (valid for entire disk).

    (7)* Calibration levels are optional fields. Do you have calibration for the probabilities from your model? E.g. is a 40% forecast a “high” probability for your method?
If yes, please provide the probability ranges for what is considered a “low”, “medium”, or “high” level. This can be provided in a separate file, or as part of the main template, labeled “X_Level”, “M_Level”, and “C_Level” fields which can take the values 1, 2, or 3. These levels represent probability calibration for a model for each flare class. With 1 meaning “low” probability, 2 is “medium” probability, and 3 is “high” probability.

        For example in the MAG4 model:
        Probabilities in range → Level
                   Prob < 0.02 → 1
        0.02 ≤ Prob < 0.18 → 2
                   Prob ≥ 0.18 → 3
