Commissioning and Ramp-up Phase

Sentinel-5 Precursor Commissioning and Ramp-up Phase milestones:

Date Events, Milestones and Activities
13 October 2017 Launch of Sentinel-5P from Plesetsk in Russia
15 October 2017 Launch and Early Orbit Phase (LEOP) finalised in record time!

The Sentinel-5P LEOP Team at ESOC:
16 October 2017 Start of Commissioning Phase. The radiator cooler door is closed and no light enters TROPOMI. Start of decontamination phase.
18 October 2017 Switch on of the payload Instrument Control Unit
20 October 2017 Science test data were down-linked over Svalbard and successfully acquired by the Payload Data Ground Segment (PDGS).

Instrument testing results showing all green!
07 November 2017 The TROPOMI radiator cooler door was successfully opened and light enters from now on the TROPOMI Instrument. End of decontamination phase and start of TROPOMI cool down.

Sentinel-5P reaches its loose formation flying position with the S-NPP (Suomi - National Polar Partnership) satellite (flying about 5 minutes behind).
08 November 2017 TROPOMI SWIR detectors reach operational temperature (140 K).
13 November 2017 TROPOMI UVN detectors reach operational temperature (208 K).
15 November 2017 First solar irradiance measurements performed.
21 December 2017 Release of first TROPOMI Level 1 and Level 2 sample data products to expert users via ftp server.
5/6 February 2018 Expert users meeting at ESTEC - first feedback from the Sentinel-5 Precursor Validation Team (S5PVT)
15 March 2018 Release of TROPOMI Level 1 and Level 2 sample data products to expert users via the Sentinel-5 Precursor Expert Users Data Hub.
19 April 2018 The Level 1B processor (V1.0) developed by KNMI (with support by SRON) has been activated in the PDGS.
24 April 2018

The In Orbit Commissioning Review (IOCR) took place at ESRIN, marking the end of the Sentinel-5 Precursor Commissioning Phase.

25 April 2018 Start of the Sentinel-5 Precursor ramp-up phase with a planned duration of 8 months
30 April 2018 The TROPOMI instrument started measuring in nominal operations baseline with a 360 orbit repeat cycle.
09 May 2018 The Level 2 processors (V1.0) developed by KNMI (supported by SRON), and DLR (supported by BIRA/IASB and RAL) have been activated in the PDGS.
25-26 June 2018 The "First Sentinel-5 Precursor Products Release Workshop" took place at ESRIN where Calibration/Validation (Cal/Val) results were presented for: Level 1B radiance/irradiance (Offline–OFFL production), Ozone (Near Real Time–NRT production), Carbon Monoxide (OFFL production), Nitrogen Dioxide (NRT & Offline production), Aerosol Index and Clouds information (NRT & Offline production).
10 July 2018
