Let’s understand difference between
‘product’ and ‘display’.
A product is the information from which the
display is created:
• Gridded data to create NCWD
• BUFR data to create NCWF 1 hour forecast polygons
or CCFP
• Created by a Weather Provider

Let’s understand difference between
‘product’ and ‘display’.
Product and ‘hard copy’ used to be the same. No longer.
A display is a visualization of the digital product, and more…
• A display turns digital products into color and line texture
• A display can write disclaimers that are not in the digital product.
• A display can show the alphanumeric information contained in an
object, and choose where to place this label.
• A display can create a single picture with TWO products (i.e.,
NCWD & NCWF, CIP Severity filtered by probability > 50%)
• A display can animate digital products (NCWF-2, CIWS

Let’s understand difference between
‘product’ and ‘display’.
• A display can integrate digital products with nonmeteorological information.
• A display can choose to show only information
pertinent to the decision maker.
• A display can turn high resolution data into categories
(of the decision-maker’s choosing).
• A display can allow users to interact and show areas
and features the user wants from many products
(Flight Path Tool)
• Displays can add confidence statistics based on
verifying past products.
• Displays will be built by government and private
entities (not necessarily the weather provider). ADDS
is only the first of many new sophisticated displays to
be developed.

Some Things to Overcome
Quality of the Gridded, Digital Products
• Until then, human forecaster produced or enhanced.
Gridded forecasts will be made official as they get
meet needed criteria.
Distribution
• Pipes need to be big enough
Proper presentation for each decision
• Many types of decision displays
• Displays and critical criteria need to be determined.
• Hardware
Grids to Text

Summary
Many products exist today because of the
variety of uses for which they are designed.
Some day a single convective 4-D forecast will
be the basis for many, many, displays and tools
tailored to their use.
Process step by step as quality increases
sufficiently. We’ll see results for evaluation.
