What is claimed is: 1. A method for evaluating sensors, said method comprising: receiving a first measurement signal from a first sensor configured to measure a parameter relating to a first apparatus; receiving a second measurement signal from a second sensor configured to measure the parameter as the parameter relates to a second apparatus, the first apparatus and the second apparatus including a plurality of wind turbines grouped together into a wind farm; comparing the first measurement signal with the second measurement signal; and determining at least one of whether the first measurement signal is inaccurate and that the first sensor has failed based, at least in part, on the comparison between the first and second measurement signals. 2. A method in accordance with claim 1 further comprising generating a warning that at least one of the first measurement signal is inaccurate or the first sensor has failed based on the determination whether at least one of the first measurement signal is inaccurate or that the first sensor has failed. 3. A method in accordance with claim 2 further comprising at least one of the following based on the generated warning: testing the first sensor; repairing the first sensor; replacing the first sensor; and substituting a replacement first sensor signal. 4. A method in accordance with claim 1 wherein the first and second apparatus are separated by distance of at least ten feet. 5. A method in accordance with claim 1 wherein determining at least one of, whether the first measurement signal is inaccurate or that the first sensor has failed is in part based on at least one of information relating to ambient conditions adjacent any of the first and second apparatus and a third measurement signal received from a third sensor configured to measure the parameter as the parameter relates to a third apparatus. 6. A method in accordance with claim 1 wherein the parameter is at least one an ambient temperature, a wind direction, a wind speed, formation of ice, a yaw angle, and a pitch angle. 7. A method for controlling a first apparatus of a group of a plurality of apparatus, said method comprising: receiving a first measurement signal from a first sensor configured to measure a parameter relating to a first apparatus of the plurality of apparatus, the plurality of apparatus including a plurality of wind turbines grouped together into a wind farm; receiving a second measurement signal from a second sensor configured to measure the parameter as the parameter relates to a second apparatus of the plurality of apparatus; comparing the first measurement signal with the second measurement signal; determining at least one of whether the first measurement signal is inaccurate and the first sensor has failed based, at least in part, on the comparison between the first and second measurement signals; and controlling operation of the first apparatus based, at least in part, on at least one of the second measurement signal, information relating to ambient conditions adjacent any of the plurality of apparatus, and a third measurement signal received from a third sensor configured to measure the parameter as the parameter relates to a third apparatus of the plurality of apparatus. 8. A method in accordance with claim 7 further comprising generating a warning that at least one of the first measurement signal is inaccurate or the first sensor has failed based on the determination that at least one of the first measurement signal is inaccurate and that the first sensor has failed. 9. A method in accordance with claim 8 further comprising at least one of the following based on the generated warning: testing the first sensor; repairing the first sensor; replacing the first sensor; and substituting a replacement first sensor signal. 10. A method in accordance with claim 7 wherein the first and second apparatus are separated by distance of at least ten feet. 11. A method in accordance with claim 7 wherein determining at least one of, whether the first measurement signal is inaccurate or that the first sensor has failed is in part based on at least one of information relating to ambient conditions adjacent any of the first and second apparatus and a third measurement signal received from a third sensor configured to measure the parameter as the parameter relates to a third apparatus of the plurality of apparatus. 12. A method in accordance with claim 7 wherein the parameter is at least one an ambient temperature, a wind direction, a wind speed, formation of ice, a yaw angle, and a pitch angle. 13. A wind farm comprising: a plurality of wind turbines; a first sensor configured to measure a parameter relating to a first wind turbine of said plurality of wind turbines; a second sensor configured to measure the parameter as the parameter relates to a second wind turbine of said plurality of wind turbines; and a processor coupled to said first and second sensors, said processor configured to: receive a first measurement signal from said first sensor, wherein said first measurement signal is representative of the parameter as the parameter relates to said first wind turbine; receive a second measurement signal from said second sensor, wherein said second measurement signal is representative of the parameter as the parameter relates to said second wind turbine; comparing said first measurement signal with said second measurement signal; determine at least one of whether the first measurement signal is inaccurate and said first sensor has failed based, at least in part, on the comparison between said first and second measurement signals; and control operation of said first wind turbine based, at least in part, on at least one of said second measurement signal, information relating to ambient conditions adjacent any of said plurality of wind turbines, and a third measurement signal received from a third sensor configured to measure the parameter as the parameter relates to a third wind turbine of said plurality of wind turbines. 14. A wind farm in accordance with claim 13 wherein said processor is configured to generating a warning that at least one of said first measurement signal is inaccurate or said first sensor has failed based on the determination that at least one of said first measurement signal is inaccurate and that said first sensor has failed. 15. A wind farm in accordance with claim 13 wherein each of said plurality of wind turbines is separated from every other wind turbine of said plurality of wind turbines by distance of at least ten feet. 16. A wind farm in accordance with claim 13 wherein said processor is configured to determine at least one of, whether said first measurement signal is inaccurate or that said first sensor has failed is in part based on at least one of information relating to ambient conditions adjacent any of said plurality of wind turbines and a third measurement signal received from a third sensor configured to measure the parameter as the parameter relates to a third wind turbine of said plurality of wind turbines. 17. A wind farm in accordance with claim 13 wherein the parameter is at least one of an ambient temperature, a wind direction, a wind speed, formation of ice, a yaw angle, and a pitch angle, said first and second measurement signals are obtained from at least one of: a sensor configured to measure the ambient temperature; anemometry configured to measure at least one of the wind direction and the wind speed; local and remote meteorological masts; local and remote weather forecasts; a sensor configured to detect ice; a sensor configured to measure the yaw angle of a rotor of one of said first and second wind turbines; and a sensor configured to measure the pitch angle of a rotor blade of one of said first and second wind turbines. 18.
