Brochure available on request

WindRose V1 loads CSV, Campbell Scientific TOA5 logger files, NOAA ISD-Lite and ISCST3 surface data, then produces publication quality wind roses, time series charts, circular statistics, Weibull energy yield screening, pollution roses with CPF source apportionment, and Gaussian plume air quality dispersion. A command line engine drives batch automation.

[ Main Features ]	Wind rose with 4, 8, 16 or 36 sectors, configurable speed classes and calms.
	Time series line charts (speed, direction or both) with auto scaling axes over a selectable one day to ten year window.
	Circular statistics, Weibull distribution, wind power density and turbine AEP and capacity factor.
	Pollution rose and CPF source apportionment, plus Gaussian plume dispersion (Pasquill-Gifford A to F).
	Animated wind rose over time, standalone or over a street or satellite map.
	Export to PNG, SVG, multi page PDF report, KML, interactive map, animated HTML and GIF, CSV and HTML.

Documentation on request

WxLog V1 is an offline desktop application for post-operation evaluation and optimisation of cloud seeding programmes. It takes raw data (gauges, grids, radar, trajectories) through rigorous statistical analysis to publication quality PDF reports, answering whether seeding produced a statistically significant increase in precipitation and quantifying the additional water yield, with a zero knowledge privacy architecture.

[ Main Features ]	Target and control OLS regression, double mass curve, permutation and ratio tests, and the WMO root ratio method.
	Causal inference: propensity score matching and Bayesian structural time series for counterfactual estimation.
	TITAN radar cell track comparison and HYSPLIT trajectory delivery scoring.
	Spatial analysis: gauge quality control, Thiessen polygons, inverse distance weighting and ordinary kriging.
	Radar visualisation (PPI, CAPPI, volume) with GIF and MP4 export, and NWP and ERA5 forecast import.
	WMO, GAO and ASCE compliance auditing, audit trails, PDF and funding proposal reports.
	Zero knowledge privacy: AES-256-GCM field level encryption and FIDO2 or WebAuthn login. Fully offline and air gap safe.
