Network status

GLOSS core network status December 2010

L.J. Rickards
PSMSL (psmsl@noc.ac.uk)

The PSMSL usually provides each October a summary of the status of the GLOSS Core Network (GCN) from its viewpoint.

An 'operational' station from a PSMSL viewpoint means that recent MSL monthly and annual values have been received and checked as far as possible, and have been included in the databank. For each of the GCN stations we have used the year of the last data entered into the databank, if any, to place the station into one of four categories:

Table 1 lists the number of stations which fall into each category for all stations. Also shown are the numbers in each category reported at previous GLOSS meetings with the category definitions adjusted backwards one, two, three etc. years appropriately.

Note that before 1993 we used the 'GLOSS90' definition of the GCN (306 stations total); from 1993 onwards we used 'GLOSS93' (308 stations total); from 1997 we used 'GLOSS97' (287 stations total); from 2002 to now we have used 'GLOSS02' (290 stations total); and from now onwards we will use ‘GLOSS10 (289 stations). These changes to the definition of the GCN are made at meetings of the GLOSS Experts and are necessary in an evolving programme.

Overall, the statistics for 2010 (GLOSS10) show a small improvement in comparison with last year. This means that there has been a slight increase in the Category 1 stations from the situation several years ago due mostly to the realignment of the GLOSS Core Network.  There is also a small decrease in the number of stations in category 4. The figures continue to indicate that ongoing work is required to develop the network further so that all stations can be Category 1, currently 64% fall into this category. However, it is known that a number of the Category 2 stations are producing good data and further efforts are needed to bring these data into the PSMSL – this is particularly true of South and Central America. One hopes that the considerable investments being put into sea level recording in Africa and in the Indian Ocean following the Sumatra tsunami will eventually be represented in these statistics – this year’s status continue the positive trend seen in last year’s statistics.
