Wireless sensor networks (WSNs) are developed in an accelerated pace during the past years. Motivated by the need of closely monitoring the forest and urban environments and accurately measuring carbon sequestration and emission, we launched two long-term large-scale WSNs: "GreenOrbs" in 2009 and "CitySee" in 2011, respectively. This paper presents our recent advances and experience on how to implement the two WSNs with stable and high performance. Some research directions are also discussed based on our observations and measurements.
