Information Geo-referencing offset in the LSA SAF MSG products will be corrected on the 6th December 2017   (2017/12/05 15:08)
 
An offset of 1.5 km North and 1.5 km West has been identified in SEVIRI Level 1.5 images for all spectral channels with respect to the reference coastline. This does not invalidate the absolute accuracy of the image data and of the MSG based products, which remain within specification (3 km).

An update of the SEVIRI Image Processing Facility to correct this offset (by shifting the SEVIRI images by 1.5 km South and 1.5 km East) will be operational on the 6th Dec. Hence the LSA SAF MSG based products will also benefit from this update.
   
     
Information New LSA SAF products available   (2017/10/30 12:09)
 

We are pleased to announce the release of new LSA SAF operational products based on MSG measurements.

Derived Land Surface Temperature (DLST) products provide 10-day syntheses of MSG/SEVIRI LST in the form of temporal composites (LSA-003A) and thermal surface parameters (TSP; LSA-003B), both with an improved spatial continuity. In contrast to individual LST observations, TSP summarise the thermal behaviour of the land surface: therefore, they are readily combined and analysed with other space-derived parameters, e.g. vegetation indices, land cover maps and burn scar maps, to additionally provide applications with thermal information.

   
     
Information MSG Toolbox v2.0 available for download   (2017/10/13 11:18)
 

The LSA SAF is pleased to announce the release of the new version of the MSG Toolbox software.
MSG Toolbox is a software intended to prepare operational LSA-SAF products for further analysis and use in GIS and Remote Sensing software, in particular by preparing temporal composites and/or by remapping to geographic lat/lon coordinate system and reformatting.

The main change in this second release is the support for LSA-SAF products with coverage of the full MSG Disk.

The link to download MSG Toolbox v2.0 can be found at https://landsaf.ipma.pt/products/toolbox.jsp

Information LSA SAF production outage   (2016/07/13 10:07)
 

Due to a power supply failure at the IPMA's facilities the LSA SAF production was suspended from 2016/07/12 18:00 to 2016/07/12 23:45.

The following products were not produced during this period:
LST, DSSF, DSLF, FRP-PIXEL, FRP-GRID, ET and FD&M.

The daily products of 2016/07/12 might also be affected by the low number of available observations during that day.
Products affected: DIDSSF, DIDSLF, DMET, MDAL, MFVC, MLAI, MFAPAR.

The FRM products were not affected by this event. 

   
     
Information Update on pre-processing of forecasted atmospheric inputs    (2016/07/07 15:28)
 

A minor bug in the pre-processing of data that serves as input to some LSA SAF products has been identified and corrected. The error was related to the reprojection of atmospheric forecast data to satellite grid in coastal regions: under some conditions the interpolation algorithm was wrongly using information from grid-points over sea.

This issue affects particularly products that explicitly use NWP forecasts, such as LST, DSSF, DSLF, ET and FRP.

The algorithm has been corrected and implemented from timeslot 2016/07/07 00:00UTC onwards.

   
     
Update New version of FVC and LAI algorithms   (2016/07/06 12:34)
 

The LSA SAF team would like to announce that the daily and 10-daily vegetation products (FVC, LAI) have been upgraded by the 6th July
The new algorithm provides a more accurate identification of the vegetation and soil components, which reduces a positive bias of FVC and LAI values for South America and South Africa regions, and also improves the consistency with other satellite based products. A new condition has been added to better identify pixels with residual snow over Europe.

   
     
Information LSA SAF: MSG production outages    (2016/05/12 09:31)
 

Due to missing MSG images most of the LSA SAF high-frequency products were not produced yesterday, 11/05/2016 between 07:00 and 12:30 UTC. This issue preceded other period with missing and delayed products (between 10:45 and 12:30 UTC) caused by a planned maintenance activity in the operational processing chain.

Important LSA SAF Products web dissemination service resumed.   (2012/06/15 14:46)
 

Following the tentative to open the web dissemination services last March, resulting in a crash of the interim storage system, a new archive system is now being tested.

For this test, a limited sample of LSA SAF data is available, namely the full year of 2010 and 2012 from 08-05-2012 13:30 till present.

For data retrieval, the only ordering method available will be the Random slot ordering.

Please allow for 24 hours for the reception of the data. If after this period the data is not available please try again.

   
     
Warning LSA SAF Products WEB Dissemination service stopped   (2012/03/09 11:40)
 

The interim storage system currently being used by the LSA SAF was unable to cope with the high volume of products requested through the WEB page. As consequence, the automatic dissemination through the WEB page was suspended and will continue so, for an undetermined period of time.

Meanwhile, the LSA SAF team will continue to process requests made directly to the Helpdesk (helpdesk.landsaf@meteo.pt ).

The project team is working on a solution to reactivate the Web dissemination as soon as possible.

We apologize for any inconvenience.

   
     
Information LSA SAF Products web dissemination service resumed.   (2012/03/07 11:19)
 

Following the problems detected in the IM Archive System, namely the degradation on data transfer, incompatible with the automatic off-line dissemination, it was necessary to suspend it, at the end of 2011 (see news on 14-12-2011).

As it was stated in the same new, a non-hierarchal new archive system, fully compatible with the next phase of operations, CDOP2 starting in March 2012, it is planned and it will be implemented during 2012.

In meantime LSA SAF products, up to 2011 and all products of 2012, have already been transferred from the IM Archive System to an external interim storage system, called SAAB, which will be used to support the automatic off-line dissemination, including web distribution services.

The transfer of all remaining products (January to December 2011), still on the IM Archive, is running and the data will be progressively made available in the SAAB.

The SAAB system has some limitations in the performance but, in general, shall be able to respond to all user requests, even if increasing a bit the response time.

   
     
Update LSA SAF Products web dissemination service stopped.   (2012/02/01 16:31)
 
LSASAF system is making use of the Institute of Meteorology (IM) archive system which is based on a 10-years old technology.

IM archive system is an expensive hierarchal solution, requiring proprietary software, which has always presented some problems, is now working in a degraded mode, incompatible with automatic web dissemination of LSA SAF products.

To increase the performance of the actual IM Archive system it would be necessary to invest a considerable amount of financial resources. Non-hierarchal archive systems are now more powerful and can be acquired at reasonable prices.

A non-hierarchal new archive system, LAS (LSASAF Archive System) is planned to be implemented and shall be fully compatible with the next phase of operations, starting in March 2012 (CDOP2). No more investment will be done in the old solution, except the strictly necessary to assure the retrieve of all data.

All LSA SAF products are being transferred from IM Archive System to an external interim storage system called SAAB (ready up to 2010). Later all data will be transferred to LAS and SAAB will remain as a backup.

The SAAB system testing is expected to be finish within the next two weeks and after that, if tests are successful, will be used to support the automatic web dissemination.

Users will be informed when the distribution web service is back.

Information New algorithm versions   (2008/05/05 16:23)
 
SDP v3.11:

 Main Changes:
- This version is prepared to compute either spectral or effective radiances, as disseminated by Eumetsat
- The central wavenumbers for MSG1 & MSG2, and the alfa and beta parameters used to convert from radiances to brightness temperatures are the ones documented in EUM/OPS/TEN/05/2556 "On the Conversion from radiances to equivalent brightness temperature"
- Attributes IMAGE_AQUISITION_TIME and PIXEL_SIZE at VAA & VZA files have been corrected
- VAA, VZA, LAT & LON are now processed for all pixels (land, inlandwater & water)
- The time field on quasi-static file names (LAT, LON, DEM, LWMASK & LANDCOV) is now the time slot of input data instead of the nominal product time

VEGA v2.1

- HDF5 attributes. The attributes have been adapted to the new definition given in the POF v2.2 (7 March 2008).

- Error of the products. The error computation has been reformulated, in order to  increase the reliability of the error bars. The current formulation is provided in the SAF/LAND/UV/VEGA_PUM/2.1.

- Product coverage and associated quality flags. One major difference of the current VEGA v2.1 version, compared with the previous one (v2.0) is that areas with low quality inputs are ot processed (in the v2.0 version problematic areas were processed and, therefore, users are advised to use associated quality information  described in /SAF/LAND/UV/VEGA_PUM/2.0- to discard unusable estimations). The use of a more restrictive threshold for masking unreliable inputs (e.g. presenting large input errors or unidentified residual snow) guarantees the reliability of the VEGA v2.1 estimates. Details are summarized in tables 7 and particularly 8 of the SAF/LAND/UV/VEGA_PUM/2.1.
