The CYCOFOS observing products are served and updated hourly. These include the in-situ water temperature and salinity and sea level. The remote sensing SST-sea surface temperature and chlorophyll-a are updated daily.

The CYCOFOS monitoring consists from in-situ and remote sensing data provided in near real time. The satellite remote sensing module of the CYCOFOS process daily satellite data for SST-Sea Surface Temperature, surface Chlorophyll-a, Light Attenuation, detection for oil slicks and sea surface zooplankton. The CYCOFOS HRPT ground receiving station has been providing regularly remote sensing NOAA - AVHRR SST images of the Levantine Basin and of the Eastern Mediterranean Sea, while for surface chlorophyll-a, light attenuation and oil slick detection MODIS images are processed, the latter obtained through NASA LAADS. These medium-resolution (250 - 500 m) MODIS data show great potential for daily monitoring of the marine environment, because of their unprecedented synoptic and repetitive coverage with a relative high spatial resolution. Moreover, added value SAR images, obtained through EMSA CleanSeaNet, are processed by CYCOFOS for restricted local end users, in agreement with EMSA.

The CYCOFOS in-situ monitoring consists of periodic short surveys and continues observations from fixed and moving platforms in the Levantine basin. XBTs surveys are carried out periodically in the SE Levantine basin using VOS - volunteer observing ships. The data collected from these short cruises jointly with other similar data from other parts of the Mediterranean are assimilated in the parent MFS model, used for downscaling the CYCOFOS flow models. The CYCOFOS in-situ monitoring at fixed locations consists from an open sea observatory and a coastal station. The first one, measures conductivity, temperature and depth at five levels in the deepest part of the SE Levantine Basin. This platform is known as MedGOOS-3 Ocean Observatory, and was deployed in June 2004 by the Harris Maritime Communication Services, who owns and maintains this observing platform. The data are collected every 30 minutes, and retrieved every 24 hours with satellite communication. They are processed and posted on the CYCOFOS web site daily. The coastal fixed platform at Paphos harbour is part of the MedGLOSS network and measures sea level, sea surface temperature and air pressure since 2001. Hourly averaged data from this coastal station are transmitted to CYCOFOS through internet.

Recently the CYCOFOS in situ monitoring capability has been enhanced by two deep ocean gliders with the capability for continuous operation up to 6 months, profiling down to 1000 meters depth. Near real time in situ profiling of temperature, salinity, currents, oxygen, fluorescence and optical backscatter in the Eastern Mediterranean Levantine Basin will be carried out using these gliders. Transects will be pre-programmed, with the opportunity to re-direct a glider several times a day to carry out a different mission. We expect to collect information on the flow of water of Atlantic origin, as well as spatial variability of the Eastern Levantine at resolutions impractical with traditional methods. Moreover, the CYCOFOS glider data will contribute to the increase of the operational observational capabilities in the Eastern Mediterranean, as well will provide an improvement of the CYCOFOS and of the MOON ocean forecasts on sub-regional and coastal scales, through the assimilation of the data from these gliders.

Periodically, sea surface temperature and drifter trajectories are obtained from various types of surface drifters in near real time through Argos. The drifters are deployed in the framework of research projects and cooperation with other institutions.
