NWCSAF General Information

 

Introduction

Background

According to the Decision of the 29th Council of EUMETSAT, the Agreement of Co-operation of a Satellite Application Facility on support to Nowcasting/ and Very Short-Range Forecasting (VSRF) was signed by EUMETSAT and INM in December 1996. The project started in February 1997 aiming to produce the Software to deal with the Nowcasting and VSRF using the characteristics of the MSG SEVIRI data and the NOAA and EPS AVHRR data.

General Objectives

The general objective of the SAFNWC is to provide operational services to ensure the optimum use of meteorological satellite data in Nowcasting and Very Short Range  Forecasting by targeted users. This is applicable to the MSG and the PPS satellite systems. To achieve this goal, the SAFNWC is responsible for the development and maintenance of appropriate SW Packages, as well as of all related tasks for user's support. Moreover, the SAFNWC intends to be a Centre of Excellence for Nowcasting in EUMETSAT.

Phases

After the Development  Phase , the EUMETSAT SAF Strategy considered the Initial Operations Phase (IOP) as a transition period from the development to the full operation phase. IOP looks for filling the gap or building a bridge between the launch of the MSG-1 geostationary satellite and the launch of the METOP-A polar satellite. From then in advance, the Continuous Development & Operations Phase (CDOP) was planned.

Nowcasting SAF involved organizations

The Nowcasting SAF belonging to the SAF Network is part of the EUMETSAT Ground Segment. The SAF network  has been developed under the overall co-ordination of EUMETSAT. Under the leadership of the Spanish Meteorological Agency (AEMet), the SAF NWC is developed by a Project Team involving Météo-France, the Swedish and the Austrian Meteorological Institutes.

IOP Objectives & Planning

  • Complete the development of the MSG products, up to their validation and tuning using real SEVIRI data, as available from the MSG mission;
  • Validate the SAFNWC/MSG products;
  • Improve the SAFNWC/MSG products and plans according to the results of the validation activities;
  • Complete the engineering of the SAFNWC/PPS package: common SW developments and integration into a single package;
  • Perform the Validation of the PPS Products using NOAA/AMSU-B and EPS/MHS data when Metop is available;
  • Deliver updated SW Packages for SAFNWC/MSG and SAFNWC/PPS during IOP as necessary to support maintenance and planned improvements;
  • Give support to users by means of a Help Desk (web site) and training activities;
  • Collect new User Requirements for further developments;
  • Implement new developments according to the upgraded User Requirement Document; and
  • Be a reference for Nowcasting aspects for EUMETSAT.

CDOP Objectives & Planning

  • Improve the quality of the products through validation activities;
  • Potentially develop new algorithms according to user requirements based on users needs and on the state of art in Nowcasting and VSRF;
  • Perform those activities aiming to ensure the applicability of the products to the MSGN area, trying to widen the applicability to other regions;
  • Cooperate with the SAF Network, EUMETSAT Central Facilities and users;
  • Improve the harmonisation of PPS and MSG to ensure that further development of similar PPS and MSG products is harmonized were scientifically possible;
  • Maintain the current NWCSAF/MSG and NWCSAF/PPS SW packages by means of corrective, adaptive and perfective activities;
  • Perform the Validation of the PPS Products with EPS/MHS data;
  • Adapt the NWCSAF/PPS SW to the NPP satellite and prepare for the NPOESS;
  • Add cloud microphysical parameters as optional output to the Cloud Type product for NPP satellite;
  • Start preparatory studies to process Meteosat Third Generation data for the next CDOP-2 phase;
  • Deliver updated SW packages according Steering Group endorsement;
  • Provide support to users by means of a Help Desk and training activities;
  • Develop an iterative process to collect new User Requirements for further developments; and
  • Being a reference for Nowcasting aspects for EUMETSAT, as a Centre of Excellence.

CDOP-2 Objectives & Planning

  • Extend the operability of its packages to other satellites and to prepare for MTG and EPS-SG;
  • Develop new products and improve the CDOP ones with relevant improvements, according to Nowcasting state of the art and user requirements;
  • Strengthen the coordination with EUMETSAT Central Applications Facilities and the other SAFs through dedicated cooperation and federated activities;
  • Reinforce the use of the NWC SAF Software packages among the meteorological community;
  • Maintain the SW packages by means of corrective, adaptive and perfective activities;
  • Provide support to users by means of a Help Desk and training activities;
  • Deliver updated SW packages according Steering Group endorsement;
  • Develop an iterative process to collect new User Requirements for further developments; and
  • Being a reference for Nowcasting aspects for EUMETSAT, as a Centre of Excellence.
