Using GIS and NJWXNET observations to study NJ mesoscale weather phenomena
The Office of the New Jersey's State Climatologist located at Rutgers University, Piscataway, N.J has put together a New Jersey Weather and Climate Network (NJWXNET) which provides hourly observations from dozens of weather stations. The enhanced network supplements the traditional ASOS network and can provide more detailed surface analysis. This project utilizes Geographic Information Systems (GIS) and various integration of physical data layers (such as landuse, digital elevation, etc.) to conduct the spatial analysis of mesoscale meteorological phenomena. The evaluation of integrating physical attributes along with real mesoscale weather conditions can lead to noticeable localized influences through anthropogenic features, such as urban heat islands and natural features, such as sea breeze fronts and mountain induced orographic lifting mechanisms.
The systematic methodology regarding importation of the NJWXNET dataset for mesoscale analysis is necessary because NJWXNET consists of different subnetworks. Each subnetwork has its own instrument characteristics and errors. The dataset is classified within the GIS via station type, and each spatial layer is set to a common coordinate system. Once the procedures are appropriately constructed, the analysis of integrating different meteorological observations with multiple landuse layers over different localized quadrants of New Jersey will be applied in order to efficiently interpret mesoscale weather phenomena.
