Looking to share your data to help us improve our models and make them applicable to your growing region? Read on for details of what sort of data can help our research.
Phenological data (including Brix)
By far, the most critical data are dates of the main phenological stages: budburst, flowering, veraison, and sugar maturity.
Ideally, we hope for:
- Budburst: green tips stage (if another stage close to this we can use, just be clear in what stage you are reporting)
- 50% flowering (we can use other percentages, just be clear in what stage you are reporting)
- 50% veraison (we can use other percentages, just be clear in what stage you are reporting)
- Sugar maturity: The models benet from all Brix measurements (multiple time points of the same block/variety are very helpful; Baume or other measures of sugar are also very useful to us).
For budburst, flowering, and veraison, please indicate which percent of the buds and/or vines are at each stage (e.g., do you report 50% flowering when most vines are at that stage?). We do not require data on all events, though the more the better. That being said, if there is only data on one or a couple of events (e.g., only budburst data) they are still useful.
For each event, we need to know (1) the date, (2) variety and (3) vineyard block. Our models allow us to use data from any variety (as long as we know which one it is), however, we are especially interested in data for: Cabernet-Sauvignon, Chardonnay, Chasselas, Grenache, Merlot, Mourvedre (Monastrell), Pinot Noir, Riesling, Syrah, Sauvignon blanc and Tempranillo.
The models work best given the most local climate data. Any data for relevant vineyards that can be accessed and shared is helpful. Ideal dates begin September 1st of the year before budburst and extend through the whole next season for each year with phenological data. The most critical measurement includes air temperature minima and maxima, other metrics that may be helpful include precipitation and humidity.
Format of data
We do not want data formatting to be a major hurdle for data sharing, so please contact us if there is an issue and we can figure it out. Our lab is able to re-format data, so our main priority is to receive the data in a way that can be interpreted. We can read most file formats or pull data from AdCon etc. if you provide us access. Please don’t hesitate to ask any questions about this!
