I had a bried discussion with Joe Glassy today.

- Now he starts implementation of the EF logic for operational production (ECS).

- We need to set up validation plan for EF products and compile it to a document soon.

this is a test. :-)

I am working on water balance applications in SE of Southamerica, and we are using transp estimates based on NOAA/AVHRR.
I wonder where can we get MOD16 transpiration estimates for this region
Thanks in advance

I will like to know the dates of first MOD16 products. Exciting to see what the product can do over our Canadian regions. I ran a satellite ET algorithm in 1991 over southern Saskatchewan (N. Bussières, R.J. Granger and G.S. Strong, 1997, Canadian Journal of Remote Sensing, 23, pp. 3-14). As part of CEOP, there is a project named "SAGE" which targets the Saskatchewan river basin. I remapped some MOD10 and MOD11 from ISIN onto our Saskachewan grid. I hope to compare MOD16 to data from our boreal study site and from our models, etc.

Maybe I first introduce myself to you; I am Wim Timmermans from the International Institute for Aerospace Survey and Earth Sciences (ITC) in The Netherlands. To keep it short, basically me, and some colleagues are working on (trying to) determine ET estimates from space for quite a while. We are using a one-source algorithm (SEBAL, by Wim Bastiaanssen) and apply this on several image types over different areas, basically in data scarce regions. At the moment I am trying to get the thing running for MODIS data as well (and validate that with eddy flux measurements in Northern Botswana, Maun).

Basically I am doing some work under the SAFARI2000 umbrella in an area over Botswana (Okavango delta), where I am trying to validate the thing as well. Apart from that SEBAL one-source model I am planning to incorporate a 2-source model also, possibly coupled to an atmospheric model as well, for which there is some support from the USDA Hydrolab.
When I examined the MOD16-presentation I wondered whether already some results are obtained with MODIS and its VI-Ts algorithm and whether thereare also validation sites outside the US (since in the presentation only mention is made of the AmeriFlux sites...)

I hope someone finds some time to answer my questions and of course I'm interested in any progress and other (parallel) developments as well...

My Name Kimaro, T.A
I am a final year PhD student at Kyoto University Japan. My research area is distributed hydrological modelling for detection effects of land use changes to river flows. I am applying a two source SVAT model at a small basin in Japan to estimate Evapotranspiration and Evaporation depending on landuse(vegetation and soil types) while searching for information on remote sensing products applicable for my work i came across this forum and was interested to join. I hope to benefit from the experience of members and contribute by sharing my experience as it gather it on my research.

My name is Wang Kaicun, a PhD student from atmospheric science department of Peking University,China. My research area is similar to Wim Timmermans’s. But my interest area is the Tibet plateau where the data is scarce and the climate is arid or semi-arid. I have read the thesis of Wim Bastiaanssen, but I think his one layer model is not suitable to retrieve ET over arid and semi-arid area. Now, I want to get information from MODIS land products, and using two-source model to retrieve ET.
I hope communicate with Wim Timmermans. My email address: wangkaicun@163.com .

I'm student in field of REMOTE SENSING and GIS in course of MSc in Iran.My thesis subject is about estimation of evapotranspiration using MODIS and IRS images.I want to test SEBAL for it.I like to relate to everyone who can help to me and also I help to him/her if I can.

Hello Hassan,
My name is Yann Chemin, I am doctorate student in the Asian Institute of Technology (Thailand).
I have been working with SEBAL since 1997 on many countries in Asia. Many people on this list are more knowledgeable than I on this topic, so if i may suggest you send queries over this list they may help you too. My student email is st027364@ait.ac.th.

I am also having some few interests about the two-source Energy Balance model of Norman and Kustas... If you are interested in comparing the two models.

Greetings,
Yann

Hello, My name is Marvin Baquero. I am Geologist Eng. At the present I am a master student in Geological Sciences at the Central University of Venezuela - South america. My research area is hydrology, specificaly in Estimating Evapotranspiration using remote sensig data - NOAA AVRRH and ground. I would like to know about MOD16 and talk with Ricardo Romero because I think we have the same project. Thanks a lot.

Dear colleagues;

We published two papers regarding to the basic concept and implementation plan of MOD16:

Nishida, K., Nemani, R. R., Running, S. W., Glassy, J. M. (2003): An operational remote sensing algorithm of land surface evaporation. Journal of Geophysical Research, 108(D9), 4270, doi:10.1029/2002JD002062.

Nishida, K., Nemani, R. R., Running, S. W., Glassy, J. M. (2003): Development of an evapotranspiration index from Aqua/MODIS for monitoring surface moisture status. IEEE Transactions of Geoscience and Remote Sensing, 41(2), 493-501.

Please note that there were some mistakes in the papers:

We are also getting ready to distribute the source code of MOD16 algorithm for MODIS data as well as NOAA/AVHRR.

FYI: Another presentation document:
Test run of MOD16 logic for AVHRR in eastern Asia.
(Presented in IUGG2003, Sapporo, Japan, July 2003)

Dear friends,
I am a Ph.D. student at the University of Durham, UK. The goal of my research is to extract surface albedo, VI and LST from MODIS to serve as parametric inputs for regional evapotranspiration modelling over the Volta basin (Ghana, West Africa - semiarid environment).

It will be great to share ideas with colleagues who possess advanced knowledge in this area. I am aware that Bastiaanssen and some of his students have applied SEBAL to Kenya, Sri Lanka, Turkey, etc. Can this be suitable for savannah catchments of West Africa? If not, are there other suitable algorithms?
My email: sopoku62@aol.com

TSEB (NORMAN and KUSTAS) and Granger method maybe of your interest... Yann

My name is Preeyaphorn. I am a doctoral student at Department of Water Resource Engineering, Kasetsart University, Thailand. For my work, I will estimate evapotranspiration using SEBAL and MODIS to calculate water balance. If you has some information and knowledge to comment and exchange with me, please sent e-mail to me. Thank you.
