Systems and Methods for Site-Based Irrigation Control

Abstract: An irrigation system is contained at a particular site, where the site may be a commercial address or a residential address. The system includes a weather station that generates temperature data, precipitation data, and any other useful data that might be used by other components of the system. The system also includes an irrigation controller that uses electrical signals to open and close valves, thereby turning sprinklers on and off, whether zone-by-zone or sprinkler-by-sprinkler. The system further includes a host device which communicates with the weather station and with the irrigation controller. The host device includes a computer processor and one or more wireless interfaces. The host device receives the weather data from the weather station and calculates an amount of desired irrigation, generating an irrigation schedule. The host device then controls the irrigation controller according to the generated irrigation schedule.

One-Dimensional Coupled Ecosystem-Carbon Flux Model for the Simulation of Biogeochemical Parameters at Ocean Weather Station P

Abstract: In this Technical Publication, we describe the model functionality and analyze its application to the seasonal and interannual variations of phytoplankton, nutrients, pCO2 and CO2 concentrations in the eastern subarctic Pacific at Ocean Weather Station P (OWSP, 50 deg. N 145 deg. W). We use a verified one-dimensional ecosystem model, coupled with newly incorporated carbon flux and carbon chemistry components, to simulate 22 years (1958-1980) of pCO2 and CO2 variability at Ocean Weather Station P (OWS P). This relatively long period of simulation verifies and extends the findings of previous studies using an explicit approach for the biological component and realistic coupling with the carbon flux dynamics. The slow currents and the horizontally homogeneous ocean in the subarctic Pacific make OWS P one of the best available candidates for modeling the chemistry of the upper ocean in one dimension. The chlorophyll and ocean currents composite for 1998 illustrates this premise. The chlorophyll concentration map was derived from SeaWiFS data and the currents are from an OGCM simulation (from R. Murtugudde).

Radiation powered battery-free energy-burst source for wireless weather stations and home-climate systems

Abstract: The power of a complete picture of energy-weather information can be used for novel energy saving algorithms in home-climate systems. Exploiting the human biological clock, we recently proposed to optimize climate systems by allowing for a correlation between inside and outside temperatures, while preserving maximal comfort. Following our earlier disclosure on a Gas Energy Observatory, we here disclose a detailed description of a battery-free wireless weather station for reliable, long-term and maintenance-free measurements. It is solar powered. Combined with energy storage in high-voltage capacitors using recently introduced low-cost step-up and step-down DC-DC converters, a versatile energy burst-source is created. Energies of a few J per day suffice for measurement, data-collection and wireless data transmission in bursts to a central data-processing device inside a nearby home. Provided as a high-volume consumer product, residential weather data can be gathered over the internet for creating a climate observation system with unprecedented areal coverage and spatial resolution at no additional cost—serving modern climate research and studies on global warming.

Irrigation Scheduling Programs of the Last Ten Years

Abstract: Various advisory software programs to assist farm managers with irrigation scheduling have been developed or older versions modified in the last decade. The fundamental procedures for irrigation scheduling are relatively straightforward and simple, but the diversity of the programs that have recently been developed is remarkable and significant. The range of analytical options offered by these programs is increasing; some have evolved from simple irrigation scheduling programs into comprehensive and sophisticated irrigation planning and management programs. Software development and the cost to maintain weather networks for its use can be inherently very complex, and oftentimes is beyond the resources of most individual states or agencies. Some scheduling efforts manage to economize by doing things such as replacing weather station networks with satellite imagery. To enhance their power and usability, various programs make use of many ancillary databases such as the NRCS Soil Data Mart, the NRCS WEB Soil Survey, NOAA weather records, aerial images, etc. This paper provides an overview of existing and developing irrigation management programs in the U.S. and elsewhere.

System of environmental monitoring of atmospheric air of mining industrial agglomeration

Abstract: FIELD: measurement equipment.SUBSTANCE: system comprises the first (1) and second (5) groups of quick-acting sensors of environmental control of atmosphere condition, a GPS system, a weather station, a mobile exchange, a central dispatcher station (4). Besides, the sensors of the first (1) group for measurement of background concentrations of chemical pollution and levels of physical contamination of atmospheric air are installed at stationary posts. The sensors of the second (5) group for measurement of concentrations of chemical pollution and levels of physical contamination of atmospheric air are installed on pilotless aircrafts (PLA), which fly around the mining agglomeration according to the set program (6). If sensors of the first (1) group detect exceeded norms of pollution, PLA are sent to areas of high pollution with sensors of the second (5) group for more detailed research of the pollution and prediction of the trajectory of its spread, depending on weather parameters.EFFECT: increased efficiency of prediction of emergency occurrence and development.1 dwg
