Click on box with feature of interest, to access a first-level slide (note: many boxes still in preparation). From there, you can navigate to 2nd and then 3rd level slides
Returns you to a second-level slide
Many images are clickable. Pass mouse over images to check if that is the case
Returns you to a first-level slide (if you are not at one already)Returns you to outline

New Horizon
• May 13– Standard products showing surface velocities and salinities can be
found at the fdb21 (best estuary model right now) RDFS site– Also useful may be the model browser. In particular, using the i button
will produce salinity, temperature and speed plots at a given point• Zoom into the estuary• In the model forecast option select “db21 forecast”• Turn off all data (scalar and vector – on the left side)• Turn on db16 bathymetry in the overlay selector (under the Legend) to see the channel• Click the i button, then select a location in the channel• View salt, temp, vel depth data at that point in the Model Profile Data Interface
– A pigeon drop directory containing some of these products is also available.
– Be aware of the forecast schedule: each day a 3 day model run is completed. The 3 days are yesterday, today and tomorrow. For example: to see the plume on May 13 use the last day of the May 12 forecast until the May 13 forecast completes.
– I’m assuming you’ll have internet access inside the estuary. If its intermittent and you’d like me to prepare some products for the next time you’re in range let me know and I’ll put it in the pigeon drop directory. -Nate
Always remember that custom products can be created upon request

• May 13-19– Plume location can be found using the cruise mapper. If you have
consistent internet access this is a good choice. Use the “dev” forecast. Charles or Alex will be able to guide you.
– A simpler alternative/supplement is to use the plume animations from RDFS uploaded to the pigeon drop location.
– We will expect to receive dye release locations from Pt Sur. We will then run drifter tracks and dye tracer runs and place them in the pigeon drop directory.
– Be aware of the forecast schedule: each day a 3 day model run is completed. The 3 days are yesterday, today and tomorrow. For example: to see the plume on May 13 use the last day of the May 12 forecast until the May 13 forecast completes.

Particle Tracking Tools
Pathway Prediction
• Images are created using a single Matlab function, invoked on the fcast00 server (requires that access be setup)
• We currently have three modes of particle tracking available• Pathway prediction• Release points evaluation• Release transect evaluation
Release Point Evaluation
• Pathway prediction option produces a figure and a text file detailing predicted position/time of the drifter
• Release position evaluation shows the predicted pathways for several release positions and times
• Release transect evaluation shows the predicted pathways for several release positions along a defined transect (formatted as in Path. Pred.)

Data: for the duration of the forecast, plot observed values of salinity versus predicted ones. Do this for fdb21, dev and fdb16 (3 curves defined by small dots, different colors)
RMSE: Foreground: For day 1 of the forecasts - RMSE of fdb16 (day) vs fdb21; ditto, dev vs fdb21 (two dots, two colors)Background: ditto, for the previous 14 days of forecast (two curves, each with 14 dots; same colors, smaller dots)
CRSTC and IOA: as RMSE

New Horizon: instructions to followPoint Sur: instructions to followLand mirror: http://www.stccmop.org//CORIE/cruises/cmop/pigeon/mirror
The directory structure is …/mirror/[date]/. Under each date will be forecast directories for the db16 (estuary), dev (plume+), fdb21 (estuary, some plume), and fca200mv (experimental) forecasts. Images from standard products can be found in these directories. Each date may also include a “modeling” directory, which will contain anything the modeling team comes up with in addition to standard products, including drifter and tracer images.
