Commissioning timeline and data release• Commissioning sequence: Launch, Early Ops, Instrument Switch-on, Decontamination, Instrument
Characterisation, transition to nominal mode operations (includes further Char&Cal, and much shorter
interruptions of calibration modes)• Each instrument has its own timeline which is still being refined.

• Start of your correlative measurements to validate an EarthCARE instrument can take place as soon
as “stable” NOMinal mode Level 0 products are generated for this instrument, well before Level 1
product release. Validation teams will be kept informed on progress towards this milestone.
• Current planned sequence of stable NOM mode operations: CPR, BBR, then ATLID, and finally MSI

Orbits and overpasses“Orbit is maintained within a deadband of 25 km each side of the reference orbit”

Reference
orbit

What does this mean?
• The reference orbit is theoretical orbit (that can be used inlong-term correlative activity planning)• The real orbit will vary East and West of this reference,
depending on solar activity (causing a drift towards theManoeuvre
Eastern edge of the deadband) and Orbit Control Maneouvres(to bring it close to the Western edge of the deadband)• The predicted orbit (available 3 days in advance) takes into
account these deviations and should be used for short-term
Real orbit
overpass planning

The reference orbit has been specified as a system requirement, but leaves one parameter free: the longitudonal shiftof the entire orbit pattern. It is intended to select a value for this free parameter a priori, to support validation sites
coverage planning.
The optimisation process for this is ongoing. Validation teams will be informed.

Communications
Validation teams will be continously informed of EarthCARE news affecting their planning (e.g., outages)
and analysis (e.g. degraded quality events)
This information will cover all four instruments: ESA and JAXA are setting up technical information flow

PIs are requested to submit progress reports on data acquisition and (once EarthCARE products becomeavailable, intercomparisons)Presentations at the validation workshops are also expected. The preliminary results workshop is split inthree parts corresponding to the staggered public release date.
Publications on pre-operational data need prior authorisation,and a clarification statement
To be discussed at this workshop: special issue?
