Dear Francisco Can one for example use a general variety( maize long season) to estimate the best planting date under irrigation, in a different country. So fertilize, irrigation is optimal, the soils are all the same? Will one be able to make a conclusion in general, thus cerain months will be better to plant maize. This is then without calibrating model for a specific variety? Thanks
Tricky question. In general the answer would be yes, a general idea on when to plant can be deduced. However, this implies that conditions in the new place are not too restrictive for growing maize, e.g. if season length is too short. Hope this helps
Thank you Sir, I am a PhD Student from Burkina Faso and I am using DSSAT 4.7 for my work. I generated my daily weather files for my location with web version of MarkSim DSSAT weather file generator for 2030s (2022-2051) and 2050s (2040-2069) time slices under RCP4.5 and RCP8.5, 30-year each. I get compressed future daily data with .wtg extension. Please I beg you to help me with how to import these .wtg data into dssat model. For example, I unzipped data into C:\DSSAT47\Weather\Gen and copied .CLI file to C:\DSSAT47\Weather\Climate but I cannot see station in XBuilt Fields section. I also try to copy data of the 30 files one by one to excel and then import and create new station with weatherman module (2022-2051 daily data) but when I go to planting section and I see that for example weather files start with 1922 to 1951 (what I expect is 2022 to 2051) for my first scenario. Thanks you.
Dear Francisco, thank you for the video. Very helpful. I was just wondering if we need to use the data for all 12 months or data for the growing season is enough? In my case it is from April to September so just these or all 12 months weather should be imported to WeatherMan?
Hello, good day and thanks for your help so far. please I was introduced to DSSAT and I need help how calibrating my model. I am working on "modelling the effect of climate change on Rice production" and help as a new person using DSSAT will be helpful. I have all my climatic data.
Thank you so much for this, but professor, you haven't shown us how to make the newly created station appear in the 'Initial Conditions' interface in DSSAT
Hi Francisco, Thank you so much for this. I have followed your instructions in this video, but when I used the weather data I created to replace the weather data installed in the model, the model did not run. Can you show me how to do it?
I have tried several times to update the weather data, but it's showing this kind of error, like date format, but I'm keeping the same date format that you have used.
Hola francisco. muchas gracias por la explicacion de tus videos. En este caso tengo una duda al cargar los datos. Cuando intento configurar la propiedad de la columna "Fecha". me aparece un cartel que dice "1.0 is not a valid floating point value" a diferencia de los datos que mostras en el video, los datos de mi estacion meteorologica arroja datos cada 30 min, por lo que tengo muchos datos del mismo dia. sera ese el problema?
Gracias Francisco, ha sido muy útil el tutorial. me pregunto si podrías continuarlo o tendrás uno acerca de proyección de clima con los datos existentes (opción Generated Data) y también uno sobre la opción Corrected Data sería muy bueno. He realizado una proyección con los datos provenientes de 2 estaciones. Quería hacer proyecciones de clima del año 2020 al año 2024, de una de las estaciones tengo datos del 2014 al 2019, y pude proyectar sin problemas las variables SRAD, TMAX, TMIN y RAIN, todo salió excelente. Con la otra estacion tengo datos del 2004 al 2008, y quise proyectar los mismos años 2020 al 2024, sin embargo, aquí obtuve sin problemas las variables TMAX, TMIN y SRAD, pero la variable RAIN en todos los días obtuve el valor -99. Obviando el problema de basarse en datos del 2004 al 2008 para proyectar datos del 2020 en adelante, me gustaría si es posble tener una respuesta técnica limitada al funcionamiento de weatherman de la razón porqué no obtuve datos de lluvia en la proyección. Si tiene que ver algo los datos de origen...Gracias...
Sir what are the respective data generated using Climagen in the form of excel file ? Sir previously there was your video showing the result in excel sheet, now as it is gone it is little bit difficult to distinghish few parameters
No excel file is generated anymore, so now ClimaGen does not require Excel to be run. The program generates directly the graphs (and the data are included in csv files)
Hola francisco. Yo importe los archivos pero cuando quiero seleccionar una estación para preparar mis experimentos no me aparece como opcional. Que puede ser?
Puede ser que necesites hacer "refresh". No puedo ser más específico porque no puedo dedicar tiempo a repasar ese tema. Por lo que sé por nuestros alumnos la cosa funciona correctamente

Maybe check your date format.
I'm sorry but never used MarkSim. Better contact the guys of DSSAT at U. Florida
you need to refresh it will appear. just have it in mind to always refresh when any change is done.
Buen video, parece muy sencillo. Pero, ¿donde conseguiste la informacion de la clima?
Please help.
In this case I got the data from the network of Junta de Andalucia (www.juntadeandalucia.es/agriculturaypesca/ifapa/riaweb/web/inicio_estaciones)
@@FranciscoVillalobos thanks a lot
Thank you so much. It has been very helpful.

Good question. I have never worked with such scarcity of data so I'm not sure. Better try yourself to see if it works with just the data you need

I'm only providing help regarding the tutorials I have produced
Thank you so much for this, but professor, you haven't shown us how to make the newly created station appear in the 'Initial Conditions' interface in DSSAT
Try "refresh"
Indeed, it worked after Refreshing, you are the best professor
Hi Francisco, Thank you so much for this. I have followed your instructions in this video, but when I used the weather data I created to replace the weather data installed in the model, the model did not run. Can you show me how to do it?
Goto "File" and then "Update LST files"
I have tried several times to update the weather data, but it's showing this kind of error, like date format, but I'm keeping the same date format that you have used.
If the format is the same then it should work

as far as I know only daily data can be imported

Para problemas en funcionamiento del DSSAT debería acudir a sus autores, yo soy un mero usuario
dear friend, when I try to change the column mesaning (data, temp, etc) always got the same result, "'1.0' is not a valid floating point". What to do?
I don't understand what you mean by column mesaning

I am getting not a valid date error how to rectify it sir
The error is self explanatory. The date format is wrong
How to download DSSAT in my pc sir
