NinJo system at the AEMet
Outline
• Project for the modernization of the
forecasting process
• NinJo system to replace the old McIDAS WS
• Status of the NinJo implementation
• Examples using Spanish data
• Digital forecast database and GFE
• Future plans

Modernization project
Background
• We are aware that the accumulated delay in automation
at the AEMET, during the last decade, has created a
difficult situation for the production activities.
• It was clear, in 2005, that a high priority of the AEMET
should be to initiate, as soon as possible, the activities
leading to a modernization of the forecasting process and
to an increase of the automation in the product
generation.
• Working Group for the Modernization of the Forecasting
Process (2005).The WG analyzed and reviewed other
forecasting systems around the world.

Modernization project
Objectives
• To develop an integrated forecasting/production
environment allowing:
• A rational elaboration of products with a predefined
quality. Final products will be obtained without the
intervention of the forecasters.
• A significant increase in the number of graphic
products. At the present moment, a primary means of
providing weather forecasts is still textual in form.

Modernization project
Fundamental elements
• The new approach will rely on three basic
elements:
• Digital Forecast Data Base (BDDP in Spanish)
• Generation of the basic digital forecast by interactive
modification of the BDDP
• Automatic elaboration and dissemination of products

NinJo system at the AEMet
NinJo: New meteorological workstation
• During 2006 and 2007 we evaluated the NinJo
versions 1.1 and 1.2 (static data)
• The main results of these evaluations were:
• NinJo can replace, with advantage, the McIDAS
system.
• Although there are some limitations at the present
moment, NinJo is a system in development, so it will
be possible to take into account Spanish requirements
for the near future.
• It will increase the production capabilities of the
AEMet.

NinJo system at the AEMET
NinJo: New meteorological workstation
• In September 2007 we initiated the activities to
introduce a new WS based on the NinJo system.
• At the present moment we have installed:
• Two data servers
• One Cinesat XRIT decoder
• Four Ninjo clients for evaluation at different
forecasting units.
• A course for administration and configuration will
take place this month.

• Now there are different data ingested into
the NinJo system:
• Conventional observations
• Numerical models: HIRLAM and ECMWF
• Radar data (only PPI for the moment)
• Satellite data (MSG)
• Lightning data

Digital forecast database
Digital Forecast Database- BDDP
• It will be the crucial element of the modernization
process.
• The BDDP stores the basic forecast using sensible weather
elements and parameters.
• It contains a picture, as detailed as possible, of the state
of the atmosphere and its evolution.
• The basic forecast is established only one time for every
forecast cycle.
• BDDP is not designed for a specific product or purpose.

Digital forecast database
• 2m Temperature, Tmax and Tmin, Tmax and Tmin
variations in 24 h, etc.
• 10 m Wind and Wind gusts
• 2m Relative Humidity
• Wind Chill and Heat Index
• Probability of precipitation at different thresholds
and periods
• Intensity and type of precipitation (rain, snow,
shower)
• Sky cover (total, low, medium, high)
• Probability of thunderstorms, fogs, etc.
• Probability of snowfall at different thresholds,
periods and the snow-rain limit.

Graphical Forecast Editor
GFE (Graphical Forecast Editor)
• This year we have started a project to implement
the GFE at the AEMet (GFE is in operation at the
NWS WFOs, USA).
• GFE is an interactive graphical forecast
preparation system for producing routine forecast
products in various formats.
• The main functions of the GFE are:
•
•
•
•
Initializing database
Viewing and editing grids
Coordination with adjacent offices
Running background programs (e.g., text generation)

Plans for near future
To clearly identify the minimum
requirements for the NinJo system to
replace McIDAS WS.
We plan to put in operation the first NinJo
WS during 2009.
To complete the development of the first
version of the BDDP.
To implement in a preoperational
environment the GFE (and the combination
of BDDP and GFE) during 2010.
