1 Introduction 1.1 Purpose of the Document


Land SAF

This document specifies the component requirements for the Hydrology SAF (H-SAF). As well as system requirements, also component requirements focus mainly on product generation features, as the main objective of H-SAF system is to provide new satellite derived products in order to satisfy the needs of operational hydrology. Present document details at component level requirements regarding products, functions, components and interfaces as they have been described in the System Requirement Document [AD 6] and associates them to system components, modelled in CDD.

2 General Description2.1 Purpose of the H-SAF

The main objectives of H-SAF are:a. to provide new satellite-derived products from existing and future satellites with sufficient time and space resolution to satisfy the needs of operational hydrology, by generating, centralizing, archiving and disseminating the identified products:

• precipitation (liquid, solid, rate, accumulated);• soil moisture (at large-scale, at local-scale, at surface, in the roots region);• snow parameters (detection, cover, melting conditions, water equivalent);

b. to perform independent validation of the usefulness of the new products for fighting against floods, landslides, avalanches, and evaluating water resources; the activity includes:

• downscaling/upscaling modelling from observed/predicted fields to basin level;• fusion of satellite-derived measurements with data from radar and raingauge networks;• assimilation of satellite-derived products in hydrological models;• assessment of the impact of the new satellite-derived products on hydrological applications.

2.2 Outlines of the H-SAF consortiumThe H-SAF participants and their roles in the Project are detailed in following list:

Table 2 - Satellite-derived H-SAF products and satellite data sources

Note: the above table is undergoing modification (for more details see also [AD 2])In addition to satellite-derived products, H-SAF will make available forecast products derived by a NWP limited-area model, so that end-users have available a back-up product at any time. The targeted forecast products are shown as follows:

Table 3 - Backup products generated by a NWP model

The Development Phase, in addition to including the activities for developing and generating new satellite-derived products, includes a Hydrology validation programme, performed by “Cluster-4”, lead by Poland; this aim shall be achieved through a complex set of activities and working programs, fully explained in details in the Project Plan [AD 2]

2.4 System Overview The H-SAF architecture is based on:

• data production centres (in Italy, Austria + ECMWF, Finland + Turkey), that:o acquire satellite data, mainly via direct reception (RT) or EUMETCast (NRT);o generate H-SAF products also with support from local databases, products from other SAF’s, locally available auxiliary/ancillary data, NWP models and climatology.o a structure for hydrological validation of all products and for generation of validation reports, physically distributed among seven countries and centrally managed and coordinated by Poland as stated in [AD 2].

• existing dedicated communication networks (regional branches of the WMO GTS, dissemination system based on connection with EUMETSAT for re-distribution via EUMETCast) for immediate dissemination of products versus operational end-users that are:

o Meteorological serviceso Hydrological serviceso Civil Protection unitso a structure, sited in Italy (CNMCA), for product centralization and archiving of all generated products and for their dissemination to scientific end-users based on an H-SAF archive connected to the EUMETSAT U-MARF via a U-MARF client.

The UML Composite Structure Diagram of H-SAF system decomposition is here reported:


Land SAF

Figure 1: H-SAF system decomposition

In this architecture, as detailed in the System Design Document, five main subsystems have been identified:

Anyway, instruments-related requirements are here adequately flagged, and this document will take into account of their evolution.

3 Specific Requirements


Land SAF

In this section the H-SAF Component Requirements are presented, following some conventions described next. 1 – Requirement CompositionEach requirement is composed of:

• Requirement Identifier: univocally identifies the requirement throughout the document following the naming convention described hereinafter.• <Requirement Title>: optional, is a short requirement description.• <Requirement Level>: describes the peculiarity in compliance with the requirement. The following values are used in this document:

• O: Optional: the requirement implementation is optional (desirable requirement);

• R: Instrument-related: the requirement is related to the availability of a specific instrument which is not certain at the time being; this aspect is described in Project Plan risk analysis [AD 2].

When not appropriately filled, the related requirement is considered as mandatory and not instrument-related.• Subsystem identifier: identifies the H-SAF subsystem specifically related to the requirement; if missing, the requirement is mapped to the whole system.• Verification Method: describes the method to be used for verifying the requirement compliance. The following values can be used:

• Analysis [A]: When verification is achieved by performing theoretical or empirical evaluation by accepted techniques, the method shall be referred to as Analysis• Review of Design [R]: When verification is achieved by validation of records or by evidence of validated design documents or when approved design reports, technical descriptions, engineering drawings unambiguously show the requirement is met, the method shall be referred as Review-of-design• Inspection [I]: When verification is achieved by visual determination of physical characteristics (such as construction features, hardware conformance to document drawing or workmanship requirements) the method shall be referred to as Inspection.• Demonstration [D]: This verification method may be used when actual conduct can verify achievement of requirements such as service and access, transportability, human engineering features and qualitative features. A requirement which is of an operational or functional nature and is not quantified by a specific measurable parameter may be verified by demonstration. • Test [T]: When requirements have to be verified by measuring product performance and function under various simulated environments, the method shall be referred to as Test; these measurements may require the use of special equipment, instrumentation and simulation techniques; the analysis of data derived from Test shall be considered an integral part of the test. When relevant, Test also gives evidence of qualitative operational performance and requirements. The performance, as proved, shall be observed and recorded.

• Requirement Description: full description of the requirement.• <Requirement Source>: optional, applicable document the requirement derives from.• <Comment>: optional field which intends to provide additional information, justification, or explanation of the requirement. Comment is for information only and is not considered part of the requirement.

2- Requirement IdentifierThe requirement identifier has been coded in this document as follows:

CR-NNNNN-XXX-YYYwhere:

CR Component RequirementNNNNN Progressive number, unique for each requirement.XXX One of the following requirement classes: FUN Functional PER Performance OPE Operational


Land SAF

INT Interface DES Design QUA Quality

RAM Reliability, Availability, Maintenance POR Portability RES Resources

TVA Test, Verification and Acceptance DOC Documentation SAF Safety

SEC SecurityYYY One of the following functional areas GEN General ACQ Data acquisition

PPR Pre-processing PRG Product generation VPR Hydrovalidation Processing REP Reporting

ARC Archiving DIS Distribution/Dissemination VMQ Validation, Monitoring and Quality Control

In order to improve the document readability the requirements have been grouped together following a two levels structure:

• First level decomposition by requirement class • Second level decomposition by functional area. This level of decomposition can be missing when not applicable or when a limited number of requirements are present within the class.

3.1 Functional requirementsAs described in section 5 “Update of product performance estimates H-SAF Development Phase” of [AD 4], requirements related to product performances state the objective performances to be reached at the end of the Development Phase. An estimate of the actual, achievable products performance is given in Table 9 of [AD 4],
