System Introduction

The CALMET module requires input hourly observation data of meteorological ground stations as much as possible, including wind speed, wind direction, temperature, height of cloud base, cloud cover, air pressure and relative humidity. In CALMET, ground station data files (SURF.DAT) can be established in two ways.

The first method is to write the required data according to a given format. It can be used when the amount of data is small.

The second is to establish by SMERGE meteorological pre-processor. SMERGE pre-processor can be used to convert measured surface meteorological time series data into NCDC format, which is compatible with CALMET model. This method is suitable for use with a lot of ground stations, where the amount of data is large.

SMERGE meteorological pre-processor can quickly convert the surface meteorological time series data into NCDC format, which is compatible with the model. However, SMERGE meteorological pre-processor adopts C/S architecture and cannot support online CALMET surface meteorological data conversion service. Therefore, it is necessary to implement further integration to SMERGE meteorological pre-processor on the basis of B/S (browser server architecture), including the integration of input files and operating parameters, the design and implementation of system control automatic operation mechanism, and the development of data storage and output interface, so as to achieve the function of online CALMET surface meteorological data conversion service.

Before using the data products provided by CALMET surface meteorological data conversion system, the user needs to make an application for registration to the team of CALMET surface meteorological data conversion system, and submit specified materials and accept all terms of the user agreement. The system administrator will review the registration application and assign the user permission if the application is get approved. Then the user can fill in the order information and calculation parameter information as required. After the system completes the calculation, the user can search in completed orders and download the calculation result. The system administrator can manage users and orders in the background. For online computing and management process, see Figure 1.
