Except where explicitly stated, this tariff refers only to the information component of the total price. Handling and delivery costs will be added, together with Internet Broadcast Fee where applicable.

2. Research Project and Educational Use

The information cost will be set to zero EUR. Any handling and delivery costs will be charged to the Research Project or Educational user.

3. Rules of the Costs Calculation

3.1 Basic concepts

The tariff for ECMWF Products is evaluated on the basis of an 'information unit' introduced by ECOMET, the EPU (ECOMET Product Unit).

The tariff is based on the cost of a global field at the resolution of the Centre's current resolution of the operational deterministic atmospheric model, independent of its representation (spherical harmonics, regular and reduced Gaussian grid, regular latitude-longitude grid).

A unit price per EPU is applied to all Products in the Catalogue. (See 4.1)

3.2 Priced Items

An item is defined as one or more fields that are priced as one entity.

Below are the definitions of item based on the different Product Sets defined in the Catalogue:

Price of Time Series

For a given dataset, the cost of a time-series is set to the cost of 8 parameters from the dataset, at full resolution, at all time steps in the time-series over the minimum area (See 3.5).

3.3 Time unit

The costing of data will be based on a time unit of :

hours for medium-range forecasts
days for monthly and seasonal forecasts with more frequent write-ups provided at no further information charge.
months for monthly mean data from seasonal forecasts
weeks for weekly mean data from monthly forecasts

3.4 Unified costing formula

The price of a requested item is based on the following formula:

EPU per item = B * A * R * E * V * D * M

where

B is the base cost, set to 20 EPUs;
A is the area factor, which is the ratio between the area provided and the area of the globe. For ocean wave fields, this factor will in addition take into account the land/sea ratio over the provided area
R is the resolution factor, defined as the ratio between the resolution of the Centre's high-resolution operational model and the resolution provided;
E is the ensemble factor, set to 1.4 see table below;
V is the valid factor, set to 1 for real-time data and set to 0 for archive data;
M is the multi-model ensemble (MME) factor, set to 1 for ECMWF products and to 1.4 for EUROSIP products;
D is the dataset factor, defined as follows:

	Set Number	Product Set	D	E
Medium-range forecast	I-i	Fields from the deterministic atmospheric model	1	1
	II-i	Fields from the global ocean wave model	1	1
	II-ii	Fields from the European waters ocean wave model	1	1
	III-i	Fields from the atmospheric EPS	1	1.4
	III-ii	Clusters from the atmospheric EPS	1	1
	III-iii	Probabilities from the atmospheric EPS	1	1
	III-v	Extreme Forecast Indexes from the atmospheric EPS	1	1
	III-vi	Ensemble means from the atmospheric EPS	1	1
	III-vii	Ensemble standard deviations from the atmospheric EPS	1	1
	IV-i	Fields from the ocean wave EPS	1	1.4
	IV-ii	Probabilities from the ocean wave EPS	1	1
Seasonal forecast	V-i	Monthly means of ensemble means	40	1
	V-ii	Monthly mean anomalies of ensemble means	80	1
	V-iii	Monthly means of individual ensemble member forecasts	40	1.4
	V-iv	Monthly mean anomalies of individual ensemble member forecasts	80	1.4
	V-v	Individual forecast runs (daily real-time)	2	1.4
Monthly forecast	VI-i	Weekly means of ensemble means	15	1
	VI-ii	Weekly mean anomalies of ensemble means	30	1
	VI-iii	Weekly means of individual ensemble member forecasts	15	1.4
	VI-iv	Weekly mean anomalies of individual ensemble member forecasts	30	1.4
	VI-v	Individual forecast runs (daily real-time and hindcast products)	1	1.4
	VI-vi	Probabilities	1	1

3.5 Minimum area

It is proposed to set the minimum area to 6 square degrees of latitude/longitude. The minimum area will not apply to archived data.

3.6 Seasonal Hindcast Products

Seasonal hindcast data are available from the Catalogue of ECMWF model archived data and products at data handling charge only, if purchased as part of and for the same products as, the real-time licence.

4. Reduced Licence fees for small service providers

The annual licence fees for the provision of ECMWF real-time data to small service providers is set to:

Condition to be fulfilled	Reduced annual licence fee
T < 3 X	X/3
3 X < T < 9 X	T/9
9 X < T	No reduction

where:

X ... unreduced annual licence fee
T ... annual turnover of the licensee's company (calendar or financial year)

The reduction would not apply to maximum information charges, or to the additional fee for Internet broadcasting or handling and delivery charges.

5. Tariffs of Web Products

The ECMWF's web products are available as a whole on an "as is" basis at a price of 28,000.00 EUR (20% of the maximum charge of 140,000.00 EUR) for all commercial users. For users paying the maximum charge the access to the web products is included.

6. Other rules (applicable to all data sets)

6.1 Unit Price (P)

A unit price of P = 0.70 EUR per EPU is applied to all Products in the Catalogue.

6.2 Maximum charge after application of discount

A maximum charge of 140,000 EUR per year will be applied.

6.3 Volume discount

The following discount scheme, based on the unit price P = 0.70 EUR, applies.

Number of chargeable
EPUs per year [N] Discount Price [EUR]

0 - 2,000 N x P

2,001 - 20,000 [2,000 + 0.6 (N - 2,000)] x P

20,001 - 200,000 [12,800 + 0.4 (N - 20,000)] x P

200,001 and more [84,800 + 0.2 (N - 200,000)] x P

6.4 Volume limit for maximum charge costumer

Maximum charge customers may retrieve up to 75 GB per day without any additional charges via the Centre's Internet link; appropriate handling charges apply if a maximum charge customer regularly exceeds the 75 GB limit.

7. Specific tariffs for Service Provider/Broadcaster licence agreements

The licence fee to be paid by a Service Provider/Broadcaster for the use of Catalogue items will be composed of the following elements:

An Information Charge as determined by the Catalogue tariff above that will include the right to use ECMWF Type A Products in order to create and provide any Type B Value Added Service to end users and broadcasters;
If required, an Additional Internet Broadcast Fee (AIBF) for the right to use ECMWF Type A Products in order to redistribute Type B Value Added Services on the open Internet or to provide Type B Value Added Services to Broadcasters, where the services are broadcast over the open internet.

The Additional Internet Broadcast Fee (AIBF) shall amount to 20% of the Information Charge, as determined by the Catalogue tariff above, and shall be charged in addition to the Information Charge. The Additional Internet Broadcast Fee shall be applied only to the ECMWF Type A Products used for the redistribution of Type B Value Added Services on the open internet and be limited to 20% of the maximum Information Charge (see 6.2). The maximum combined Information Charge and the AIBF is therefore 120% of the maximum Information Charge. The AIBF will not be subject to the reduction of the Information Charge for small service providers.
