OpenWeather Agro changes that by bringing all those data points into a single conversation with your AI. Instead of hunting for a specific frost risk or trying to interpret raw satellite imagery, you can just ask your agent what your fields look like right now. It pulls in the actual numbers you need, like Growing Degree Days for tracking crop development or specific soil temperatures for planting, so you can make calls on the fly. If you're trying to manage irrigation across multiple zones, you can get evapotranspiration rates to see exactly where the water is going. Because Vinkius hosts this Connector, you can connect it once and have your agent act as a specialized agricultural meteorologist. It's about moving from looking at data to actually making decisions based on it. You get a clear picture of crop stress and development stages without the manual math, letting you spend more time in the field and less time staring at dashboards. ## Tools ### get_crop_health_index Get a single metric for overall crop health to prioritize scouting missions and communicate status. ### get_evi Access the Enhanced Vegetation Index for monitoring high-biomass regions where NDVI might saturate. ### get_evapotranspiration Calculate crop water use rates to manage irrigation and assess drought stress. ### get_frost_risk Get risk levels and predicted frost timing to plan protection for sensitive fruits or vineyards. ### get_growing_degree_days Calculate heat accumulation to predict crop development stages and pest emergence. ### get_historical_ndvi View time-series vegetation health trends to detect stress and recovery patterns over a season. ### get_ndvi Fetch Normalized Difference Vegetation Index values to monitor healthy vs. stressed vegetation. ### get_satellite_imagery Get imagery metadata and URLs for visual field assessment and boundary verification. ### get_soil_temperature Check satellite-derived soil thermal conditions to see if it's warm enough for seed germination. ### get_weather_forecast Retrieve 5-day weather forecasts to plan planting schedules and irrigation windows. ### get_weather_history Retrieve past weather data to compare current conditions with historical patterns. ### get_current_weather Pull real-time conditions for daily farming decisions like spray timing or harvest planning. ## Prompt Examples **Prompt:** ``` Is there a risk of frost in my vineyard tonight? ``` **Response:** ``` Checking frost risk for your vineyard location... **FROST RISK: HIGH** tonight. * **Predicted low temperature:** -1.8°C (28.8°F) around 5:00 AM * **Soil temperature:** 4.2°C * **Wind speed:** 2 km/h **Recommendation:** Activate frost protection measures immediately.

Your AI agent can use this to suggest specific irrigation schedules based on actual plant needs and current weather. **Can I use OpenWeather Agro to monitor crop health from my phone?** Yes. Since it connects to your AI client, you can ask for crop health scores or NDVI trends via any compatible app, making it easy to check your fields while on the move. **Does OpenWeather Agro provide frost warnings for specific locations?** It does. You can ask your agent about the frost risk for your specific coordinates. It returns risk levels like high or critical, along with predicted timing and suggested protection measures. **Can I see my field's progress over several seasons?** Yes, the Connector can pull historical NDVI data. This lets you compare this year's vegetation health against past years to see how your land is performing over the long term. **What kind of weather data does OpenWeather Agro pull for farming?** It fetches real-time conditions, 5-day forecasts, and historical weather. This helps with everything from daily spray timing to long-term harvest planning. **Is OpenWeather Agro good for tracking crop maturity?** It's great for that because it calculates Growing Degree Days. This tells you how much heat your crops have accumulated, which is the standard way to predict development stages and harvest dates. **Can my AI check NDVI for my field to assess crop health?** Yes! Use the `get_ndvi` tool with your field coordinates and a date. NDVI values range from -1 to 1, with 0.6-0.9 indicating healthy dense vegetation and 0.2-0.5 indicating stressed or sparse vegetation. For trend analysis over a growing season, use `get_historical_ndvi` with a date range. The data comes from satellite imagery processed by OpenWeather algorithms. **How do I calculate irrigation needs using evapotranspiration data?** Use the `get_evapotranspiration` tool with your field coordinates and date. ET values show how much water your crops are losing through transpiration and soil evaporation. Compare ET with rainfall (from `get_current_weather` or `get_weather_forecast`) to determine irrigation deficits. If ET exceeds precipitation, irrigation is needed to replace the difference. For precise scheduling, track daily ET over time and accumulate deficits. **Can I get frost warnings to protect my crops?** Yes! Use the `get_frost_risk` tool with your field coordinates. It returns frost risk levels (low, moderate, high, critical) based on temperature forecasts and local conditions. For proactive planning, combine with `get_weather_forecast` to monitor approaching cold fronts. High or critical frost risk indicates you should activate frost protection measures like irrigation, wind machines, or covers.
