1. Opening Remarks (Dr. Tateishi)
2. Discussion on Standard Products
3. Discussion on Research products
4. Others

• explained about discussion topics: confirmation of validation responsibility for standard products and research products; who will be responsible for validation for standard products and production and validation for research products.

• standard products; precise geophysical positioning, atmospheric correction, retrieving vegetation index and mosaicing

• candidacy of validation site

Q (Dr. Shimoda): What about Paso (tropical forest)?
A (Dr. Honda): It is possible.

Q (Dr. Tateishi): Can you find any homogeneous agricultural field bigger than 2 km x 2 km in Vietnam?
A (Dr. Duong): Yes. we can find coffee, tea plantations and mangrove fields. And there are also tropical woodlands.

Q (Dr. Tateishi): What about Siberia?
A (Dr. Honda): In winter time we cannot conduct any research due to the weather conditions.

Q (Dr. Tateishi): What about Australia? Is there any homogeneous site available for validation?
A (Dr. Prata): We have arid sites and desert sites (e.g. one desert site: Amburla). And we have woodland. It is good for validation in dry seasons. The place name is Thangoo.

Q (Dr. Prata): What are minimum requirements for the standard instruments?
A (Dr. Honda): We will require ground reflectance data, spectro measurements, atmospheric data and if possible meteorological data.

Q (Dr. Prata): Ground reflectance from one angle.
A (Dr. Honda): Well, we measure it from many angles in most cases. It is difficult to tell.

Q (Dr. Tateishi): How frequently do we implement validation?
A (Dr. Honda): Basically once a month; but usually we need automatic system to do so.

Q (Dr. Tateishi): Do you have any idea about the timing of the validation after launch?
A (Dr. Honda): It depends on versions.

Q (Dr. Tateishi): Do you validate vegetation index directly by comparing it with ground vegetation index?
A (Dr. Honda): Yes, we can directly compare two of them. Or we can use high-resolution satellite data as a supplement data, and then compare it instead of ground vegetation index with GLI data.

• research products; vegetation distribution, speed of forest decrease, fAPAR, LAI, biomass, NPP, land cover and use, land surface temperature, albedo, biomass and fire.

Dr. Prata's Comments: I am responsible for land surface temperature and albedo. But, we can't validate snow in neither case. Maybe Dr. Honda can help me in that respect.
A (Dr. Honda): Yes. I can help you.

Dr. Duong's Comments: For land cover and use, I can be responsible. But, I also need some help from other PIs.
Dr. Tateish's Comments: I am also responsible for land cover and use.

Dr. Prata's Comments: (talking to Dr. Duong). I can send you digital information of my sites.

Q (Dr. Tateishi): Vegetation and land cover are similar in terms of validation method.
A (Dr. Duong): Yes. They are similar.

Q (Dr. Tateishi): How does JAXA treat research products in relation with standard products?
A (Dr. Honda): JAXA treats the research products as semi-standard products, which can potentially turn into standard products if their performance is good enough.

Q (Dr. Tateishi): Who can generate GLI data for other products?
C (Dr. Honda): We can generate GLI information on fAPAR, LAI, biomass and NPP.
But, we cannot provide any forest data because our site (Mongolia) doesn't have any forest site.

Dr. Prata's Comments: Dr. Michel is conducting GLI research on fAPAR.

Dr. Honda's Comments: We have to ask each PI at different sites what kind of validation data they can provide.

Dr. Tateishi's Comments: I am not concerned about validation as much as about production.

Dr. Honda's Comments: Each PI should develop his/her algorithms for his/her site.

Q (Dr. Tateishi): Who can be responsible for development of research products such as biomass data set?

Dr. Prata's Comments: There are two categories for biomass fire; recognition of burned area and hot burning fire.

Q (Dr. Tateishi): Are you interested in NPP, Dr. Muramatsu?
A (M): Yes.

Q (Dr. Prata): What do we do about the fire?
A (Dr. Tateishi): We are not sure yet. But, we don't have to decide the matter now.

Q (Dr. Prata): What about validation plan?
A (Dr. Honda): PIs responsible for each product have to develop each validation plan. And later we will put them together and will ask you to do final correction on the plan. We will also conduct cross-checking with other groups.

Dr. Tateishi's Comments: Vegetation distribution and land cover and use can be connected together.

Dr. Vu Saito's Comments: We are preparing the system at Roppongi in Tokyo for assisting PIs in terms of data processing and distribution. Please make the most use of our facilities.

Q (Dr. Vu Saito): Do you have any mechanism to coordinate these activities which we discussed today?
A (Dr. Prata): We have the system, which Dr. Honda explained earlier. Each PI will write up a validation plan, and then Dr. Honda will be responsible for coordinating the plans.

Dr. Tateish's Comments: I want Dr. Honda to be a coordinator in this project concerning the production and validation of research products. I will be responsible for land cover. But I am not sure about vegetation distribution at this stage.

Dr. Tateishi's Comments: I think you need information and response from PIs about reformatted GLI data. I will send them to you at the end of the next week.

Dr. Hashimoto's Comments: We have to consider calibration for band to band registration.
Q (Dr. Tateishi): Can you be responsible for that?
A (Dr. Hashimoto): Yes. I will try.
