GLaSS newsletter banner
Dear reader,
The good news is that in the last months GLaSS has been generated several new public deliverables, all worth reading. So we will not keep you distracted too long with this newsletter, just provide you a short overview of the results. You can use the direct links in this newsletter, or download everything from the download page on our website.
The sad news is that GLaSS is coming to an end. We have a few more months to go during which training material will be developed. We will finalise with a joint seminar with the project GloboLakes in Stirling on 20-21 January 2016, showing all our results. If you are interested to participate, feel welcome, but please contact us, there is limited space.
Best regards,
The GLaSS team

Global lakes use cases

The GLaSS core system and tool, algorithms and validation results were combined in the global lakes use cases, to show the possibilities of Earth Observation to a large audience. Lakes were grouped according to their optical properties or 'colour': green, yellow, brown, bright, dark. The colour is an indication for the ecological status and often also for its potential ecosystem services. The GLaSS use cases show what Earth Observation can provide to analyse and monitor the status of these lakes, with global showcases ranging from Scandinavia to Mediterranian, US to Himalaya, and Middle-East to Africa. Extra focus went to how Earth Observation can be used for Water Framework Directive (EU) reporting.

Use case 5 report: Mine tailing ponds: methods for continent wide screening (expected later this month)

Field campaigns and Sentinel 2 validation
This summer, GLaSS has carried out several field campaigns: in Estonia (TO), Finland (SYKE), the Netherlands (WI), Italy (CNR) and especially in Sweden (Lake Vänern), where the complete GLaSS consortium participated in a joint campaign with the GLoboLakes group. Also, the first Sentinel 2 images became available. Our partners at CNR had a matchup with their field campaign in Lake Garda! The S2 image below shows the bay Mariestadssjön in Lake Vänern the day before our joint campaign.

The validation results are being finalised, this report is expected to be available early January.
Validation of the Geoland HYPE model
The hydrological HYPE models simulate daily water discharge and monthly nutrient transport. For several European lakes time series of nutrient data were compared with MERIS satellite chlorophyll products. There were clear visible relationships between the model and the Earth Observation (EO) data. EO-data could be used as input to further develop the HYPE model. The output of a more realistic model could also serve as a gap filler where EO data is sparse or missing.
