SMOS data dissemination maintenance - 22 July 2019

19 July 2019

A planned software maintenance activity will affect the SMOS data dissemination service on Monday 22 July during the following times:

  • From 09:00 to 11:30 CEST – no access to the SMOS data collections.
  • From 11:30 to 13:30 CEST – ingestion / publication of new products delayed.

Swarm Charlie: VFM issue on 15 and 16 July 2019

19 July 2019

An anomaly occurred on the VFM (Vector Field Magnetometer) on board the Swarm Charlie satellite between 14:09:06 on 15/07/2019 and 13:29:34 UTC on 16/07/2019.

As a consequence, the production of L1B Magnetic and Plasma data, and of Level 2 - Cat 2 FAC and IBI data will be affected for this time window.


Swarm Charlie: Data gaps on 15 and 16 July 2019

19 July 2019

Several tests were performed on the Swarm Charlie satellite on 15 July in order to investigate the anomaly that occurred on 28 April.

During these tests the instruments were switched off and on, causing data gaps for all the L0, L1A, L1B and L2-Cat2 products.

In particular the following data are missing:

  • GPS data from 15/07/2019 between 04:40:01 and 10:00:31 UTC
  • STR data from 15/07/2019 between 04:48:29 and 09:31:57 UTC
  • ACC data from 15/07/2019 between 04:48:28 and 12:53:32 UTC
  • VFM data from 15/07/2019 between 04:48:27 and 12:43:10 UTC
  • EFI data between 15/07/2019 at 04:47:40 UTC and 16/07/2019 at 07:20:31 UTC

Swarm Charlie: data gaps from 28 April 2019

06 May 2019

We would like to inform Swarm users that an on-board anomaly occurring on Swarm Charlie caused data gaps on all L0, L1A and L1B data products from 28 April 2019 onwards.

In particular, GPS and STR data are missing from 28/04/2019 06:53 UTC to 30/04/2019 13:50 UTC; and ACC, MAGNET and PLASMA data are missing from 28/04/209 06:53 UTC to 02/05/2019 17:36 UTC.

Upon re-establishing a safe operational platform configuration and recovering all payloads to their nominal functioning, the Swarm team is now investigating the exact nature of the anomaly aiming at minimising the loss of redundancy caused by the failure.

Wadi System of Dhofar

On 19 March 2014 and 30 March 2018, Proba-V observed a wadi system in the Dhofar region of Oman. Originally, the Arabic term ‘wadi' referred to ‘valley', but nowadays it refers to dry riverbeds that only contain water after heavy rains.

The branched Dhofar wadi system is visible in white, just to the south of the Rub'al Khali or "Empty Quarter", the largest contiguous sand desert in the world which is visible in yellow.

The red dots in the images are pivot irrigation fields of the Shisr/Wubar oasis. For about 15 centuries, this agricultural oasis and caravan site was a very important water supply station for the frankincense transportation routes from the inland to the ports along the coast.

United Nations, World Population Day

In June, the UN Department of Economic and Social Affairs published their 26th round of population estimates and projections in their report entitled "World Population Prospects 2019: Highlights". Based on the analysis of demographic data for 235 countries or geographic areas, the report concludes that the world's population is expected to rise by to 9.7 billion in the next 30 years and to reach a peak of nearly 11 billion around the end of the century.

And, with many of the fastest growing populations living in the poorest countries, the expected growth will likely bring more challenges to meet the sustainable development targets in eradicating poverty, combating hunger or bolstering healthcare and require important investments in education.

The report's projections earmark Nigeria as the country with the second largest population increase, just after India. The Nigerian city 'Lagos', shown in this Proba-V 100 m image (dark red tones), is currently the 8th fastest growing city in Africa and it is expected to further double its population by 2050.
