Minimize Ordering Within Emergency ADDitional Datasets

The Copernicus Emergency Satellite Tasking (REACT) service is operated by ESA to coordinate the rush ordering and delivery of new and archived imagery, covering a wide range of emergency situations throughout the world upon request from eligible Copernicus Services (mainly the Emergency and Security services)

Authorised Copernicus Service Projects (CSPs) can submit emergency requests for natural disasters, including situations such as flooding, earthquakes and volcanic eruptions, as well as manmade disasters such as oil spills and humanitarian crises. These requests can include one-off or repetitive (crisis monitoring) rush satellite tasking, processing and NRT dissemination and archived data to be used as reference.

The emergency ADDitional datasets listed in the Data Access Portfolio cover optical and radar imagery in a broad range of resolutions, both for new tasking and archive imagery. Each authorised Copernicus Service will receive quotas for required datasets; available quotas can be viewed in the Data Provision section as well as the Copernicus User's Personal Area.

Emergency requests are managed through dedicated procedures by the Copernicus Emergency Satellite Tasking (REACT) team. The service is available 24 hours a day, 365 days a year to manage emergency activations, including handling the Earth Observation (EO) data requests, identifying the Copernicus Contributing Missions (CCMs) that can satisfy the requirements, interfacing with the Copernicus Contributing Mission Entities (CCMEs) to secure an acquisition in the shortest time possible and searching the archives for a pre-disaster or very recent image. The procedures followed by the REACT team are summarised below:

As shown in the schematic diagram, the activities within an emergency activation are:

  1. The authorised CSP submits an EO data request through SPERF (Service Project Emergency Request Form) Online, accessed through the SPERF menu on the Copernicus User's Personal Area. The user must provide details of all parameters of the order, including data type requested (Optical/Radar, resolution, new/archive) and area of interest
  2. The CSP follows up the SPERF submission with a telephone call to alert the REACT team to the emergency activity
  3. REACT Operator acknowledges receipt of the request within 30 minutes
  4. REACT Operator alerts all CCMEs about the new activation
  5. For new acquisitions, the REACT Operator performs a feasibility study to determine the first suitable mission that can cover the AoI. In the case of archive requests, the REACT Operator searches the CCME archives for the most suitable image
  6. REACT Operator prepares relevant order forms and sends them to one or more CCMEs within 3 hours from the acknowledgement of the activation
  7. CCME(s) provide feasibility report for new tasking requests or confirmation of archive orders
  8. Once orders have been confirmed, REACT Operator provides a Satellite Resource Table (SRT) to the CSP, containing details of all ordered scenes and planned acquisitions. This document is updated regularly during the activation to keep track of ordered and delivered EO products
  9. CCME(s) deliver the requested archive or newly-acquired scenes via their FTP and circulate the product to Coordinated Data Access System (CDS) for the creation of a single repository per activation, to be accessed by the originator of the request or other authorised Copernicus Users

Step-by-step instructions for the process of submitting requests for EO data within emergency ADDitional datasets can be found in the SPERF Online guidelines document.
