IOCCG Report 3

Cover The IOCCG is pleased to announce that IOCCG Report Number 3 entitled Remote Sensing of Ocean Colour in Coastal, and other Optically-Complex, Waters has been published. Dr. Shubha Sathyendranath edited this comprehensive report with contributions from many other experts in the field.

Report 3 is available in PDF format on the IOCCG website. Those already on the IOCCG mailing list will be sent a copy via surface mail (approximately 3 months for delivery). If you are not on the mailing list and would like to receive a copy, please reply to the following e-mail address and give your full mailing address.

Turkey Ocean Colour
Training Course

A training course on Remote Sensing of Ocean Colour was successfully held from the 11th to 22nd of September at the Institute of Marine Sciences, Middle East Technical University (METU), in Turkey.

Sponsorship for the course came from the IOCCG, the NATO Science for Peace Sub-Programme, METU and the Turkish Scientific and Technical Research Council (TUBITAK). This funding enabled thirty students and twelve lecturers from a total of fourteen different countries to participate in the course. Please consult the training course section for a report on the course.

POLDER Project has new
set of Ocean Colour data

POLDER dataThe POLDER Project (CNES) has reprocessed 8 months of POLDER data, from November 1996 to June 1997, to improve ocean colour results. The results show lower global chlorophyll concentrations and are cleaner (better clouds filter, more severe optical thickness threshold, better atmospheric correction, and change in the bio-optical algorithm). Although the derived water reflectance at 3 nm was not used in estimating chlorophyll a due to its sensitivity to errors in calibration and atmospheric correction, it is currently being worked on.

OSMI Acquiring Data

OSMI imageThe Korean earth-observing satellite, KOMPSAT-1 has been operating successfully since its launch on December 21st, 1999. The satellite has two earth observing sensors: EOC, a high-resolution panchromatic sensor mainly for land observation and OSMI (Ocean Scanning Multispectral Imager), an ocean color sensor. The OSMI mission on the KOMPSAT-1 satellite aims to collect data globally. It has six bands (412, 443, 490, 555, 765, 865 nm as the standard). The position and width of the bands can be adjusted.

To date, OSMI has acquired about 2400 global scenes. Preliminary analysis of the data suggests there may be a few anomalies related to sensor characteristics. This calibration problem has delayed routine processing of Level 2 and Level 3 data. Vicarious and inter-sensor calibrations are currently underway to remedy this problem. Data from the OSMI sensor will be available to users once the problem is solved. The image shown was collected over the Argentinean coastal region on June 6th, 2000.

MODIS Update

The GES DAAC(Goddard Earth Sciences Distributed Active Archive Center) released its Level 2 MODIS products (local scenes) on October 13, 2000.

MODIS Products released include:

  1. MODIS/Terra Ocean Color Radiance Products
  2. MODIS/Terra Ocean Color Derived Products Group 1
  3. MODIS/Terra Ocean Color Derived Products Group 2
  4. MODIS/Terra Sea Surface Temperature Products
  5. MODIS Level 2 Ocean Color QC for Production of MODOC (MODOCQC)
  6. MODIS/Terra Sea Surface Temperature QC Products

Chinese Ocean Colour
Satellite Launch set for May

China has tentatively set the launch date of HaiYang-1, China's first ocean colour satellite, for May next year. To prepare for future applications of the satellite, China's National Ocean Administration (SOA) has started construction of one of its two ground stations, that is located in Sanya, Hainan Island. The another ground station is to be located in Beijing.

New SeaWiFS Evaluation
Products Available

The SeaWiFS web site has a new category entitled "Evaluation products". These are data products released by the SeaWiFS Project that have reached a stage where they are ready for evaluation by the research community. The evaluation products are only available as Level 3 Standard Mapped Image products.

The first Evaluation product to become available is SeaWiFS Photosynthetically Active Radiation product, based on an algorithm created by Robert Frouin.
