Crop Weather Analyzer
Crop Weather Analyzer is a weather import/analyzer utility to update daily historical weather files in CroPMan from web-based weather station network or user-collected weather data. It also allows a user to create and update his/her own long-term weather file for anywhere in the world. Once weather data is formatted into a CroPMan/Crop Weather Analyzer format via the Weather Filter feature, the data can be scanned for missing days/data and edited with the weather data editor. Crop Weather Analyzer operates in both Metric and English units.
The Weather Analyzer feature calculates cumulative growing degree units (GDUs) (using CroPMan, Standard or User-defined base temperatures and upper limit temperatures) and cumulative precipitation as well as total precipitation, average temperature and average minimum and maximum temperature on a yearly/monthly basis. The user selects the period of interest for analysis (start and end date) and can compare up to two years of data with that of the long-term average over all years in the selected weather file. The program can substitute any missing data (i.e.: data from the current day to the end of the year) with average long term weather data derived by calculating the daily average for each of the weather parameters across all years in the weather file. Within Weather Analyzer the user can overlay crop growth stages for major crops (corn, grain sorghum and cotton) on cumulative GDU graphs and compare the crop development for the current year with that experienced in any previous year and the historical average. This may help the grower anticipate/predict the timing of key phenological events and improve his ability to make pest and/or crop management decisions.
Crop Weather Analyzer is distributed on CD-ROM or may be downloaded and installed from the CroPMan web site. It operates under Windows® 98, 2000, and XP. Crop Weather Analyzer can be operated in the absence of the CroPMan program; however, if CroPMan weather files are to be used, CroPMan must also be installed on the computer in order for the Crop Weather Analyzer program to have access to CroPMan databases.
