WHAT IS IN-SITU OBSERVATION? (1/5)

• In-situ observations are on-site local measurements of sea water

properties.

• They are obtained using ad-hoc on-site sensors on board of various

platforms like buoys and ships for example to capture ocean variability

at different scales. • In-situ observations are made locally. CMEMS In-Situ TAC gathers them

into ONE data base.

• INSTAC data provide a global picture of 3D ocean state and ocean

variabilty based on the integration of thousands of local data.

Marine Monitoring

WHAT IS IN-SITU OBSERVATION? (2/5)

• Many organizations outside of CMEMS acquire in-situ data in different

locations at sea.

• CMEMS’s job is not to acquire in-situ data and CMEMS does not

operate or maintain any observing systems. It is rather to gather and

integrate them into ONE DATA BASE.

• « Gathering data » from outsider organisations requires strong mutual

agreements.

• « Integrating data » into ONE data base requires strong format

standard definition and quality control procedures.

WHICH PARAMETERS? (1/3)

CMEMS INSITU OBSERVATIONS provide products with the

following parameters: •Surface and at depth TEMPERATURE •Surface and at depth SALINITY •Surface and at depth OCEAN CURRENTS •And also •SEA LEVEL •WAVES (height, period and direction), •BIOGEOCHEMICAL (Dissolved oxygen, chlorophyll, etc )

Marine Monitoring

WHICH CHARACTERISTICS? (2/3)

• In-situ observations are made locally at different places to capture

ocean variability at different scales –from local to global- and at

different depths. CMEMS In-Situ TAC gathers them into ONE data

base, hence providing a global picture based on the integration of

thousands of local data (L2 discreet in-situ products).

• To get a global picture of the ocean based on multiple local data,

CMEMS In-Situ TAC combines in-situ data into an Objective Analysis

(L4 gridded -interpolated into a regular grid- in-situ products).

▪Data integration: CMEMS gathers in-situ data from many non-homogeneous sources into ONE DATABASE. ▪Formating

▪NetCDF format ▪Uniform metadata based on internationally agreed vocabularies and standards

▪Quality control and duplicate check ▪Delete the duplicated data ▪Run automatic quality control checks on NRT products

▪Synchronization between regions to ensure similar level of service in all regions ▪L2 and L4 products: L2 in-situ discreet products are provided, but also L4 gridded in-situ interpolated products by performing an Objective Analysis. ▪Validation: REP products are scientifically validated following a thorough methodology.
