Test site describtion 116 53-118 09 E 23 32-25 13 N the annual average temperature is 21 The area is 12897km 2, 77% is below the height of 500m. Main land use type: $ arable land (12.91%) $ garden plot(13.45%) $ forest(52.49%) Zhang Zhou 2004-5-6 11

Main agriculture land use types! Crops (rice, sweet potato, potato, sugarcane... )! Vegetable garden! Orchard (bananas, litchi, longan, orange and grapefruit... ) 2004-5-6 12

Rice Growth season of all crop types spreads all year round, from spring to winter. The rice growth calendar is approximately from April to October. 2004-5-6 13

Bananas In Zhangzhou, banana is planted extensively and is provided all the year, and reached its production climax during June or July. 2004-5-6 14

Litchi and longan The trees are Evergreen, bloom in spring, ripe in summer/autumn. Litchi and longan are similar in growth and fruiting habit 2004-5-6 15

Orange and grapefruit 2004-5-6 16

narcissus the growing period of Narcissus is about 3 years, it grows best during December, After that the leaves begin to turn yellow and wither 2004-5-6 17

Ground data! Field survey is no problem during 2004-2005.! Rice phenological stages may be collected.! As for the collection the rice yield for sampled fields, we have to contact with local government. So it s impossible to decide whether we could collect the data now. But the historical total area and yield for main crop of every county will be collected. 2004-5-6 18

Some extended studies(1)! Xiamen local government pays much attention to this cooperation, and hopes some relevant units in Xiamen may participate in our project.! Relevant units: " Information Center of Xiamen Environmental Protection Bureau " Key Laboratory of Marine Environmental Science, Xiamen University " Third Institute of Oceanography, SOA (State Oceanic Administration) experience in ocean color remote sensing 2004-5-6 19

Some extended studies (content)! Coastal water quality (like suspended sediment, chlorophyll ) with ocean color sensor MERIS! Sea surface temperature (AATSR)! Shallow water bathymetry with SAR/ASAR 2004-5-6 20

Relevant studies! ERS SAR & Jers-1 SAR processing " Ortho-rectification " Speckle noise suppression " Data fusion for SAR and TM! Relevant studies in Zhangzhou district 2004-5-6 21
