How do I add future climate data (2021-2030) to my project? I'm not using the automatic catchment delineation.

Dear Rodriga,
You can add this for each of your catchments in the Climate tab as a CSV file. The number of climate inputs you can enter (precip, temperature, wind speed, humidity, etc) will vary depending on the catchment calculation method you choose in the Advanced tab.

Can WEAP download and add future climate data say 2020-2099 by itself in the catchment delineation mode?

Currently, future climate data (CMIP5) is directly accessible through WEAP, but only for the continental United States. We are working on a global dataset (CMIP6), and hope to have it ready within a month or so.

Dear Mam, I am using WEAP-MABIA method for catchment agriculture demand , I want to predict the future water demand.
Is there any tutorial available for the same?

To learn more about using MABIA, please see the WEAP-MABIA tutorial link on our WEAP Tutorial page (https://www.weap21.org/tutorial/). Note there is a separate link for the dataset.
To predict future water demand, first calibrate your yields to observed data using historical climate. Then, input your future climate and land use data in your catchments to observe the impact on yields. Note that if crop areas, crop choices, or irrigation schedules are predicted to change, you will need to enter in new information for your climate change scenarios.

We now have CMIP6 worldwide future climate projection data through 2100 integrated within WEAP. Too input future climate data into WEAP, see below:
If you created your catchment objects using automatic catchment delineation, then you can enter into Schematic --> Catchment Delineation Mode, select Load Climate Data and you can select CMIP6 scenarios, which include a variety of climate change models out through 2100. You also have the option to use a NetCDF file instead. You can see that in the Data screen, several climate variables, specified in the Select Climate Data Source from the previous step, have ReadFromFile expressions which reach in the CMIP6 data. You can save these expressions to load different climate projections in different WEAP scenarios. This thread has some useful explanations: https://www.weap21.org/index.asp?action=9&read=4546&fID=30
If you created your catchment objects manually, then you can either create climate input series using the above method, or by entering in a ReadFromFile expression into your catchments using data you have already saved into a CSV time-series.
