  • To do this you will need to select "Cancel" on this window
  • Then from the menu bar select: Data > Meteorological > Edit Database
 Slide 2 image. See text below.
  • After selecting Edit Database this screen will appear
  • To add a new City you need to choose Add New
  • The following Slide shows the data entry screen that appears
 Slide 3 image. See text below.
  • Enter the city / town and province your facility is in
  • Then enter the monthly meteorological data required. This information can be obtained from your weather office or by visiting:
  • Once all the data has been entered select "Save" to add it to the database
  • To exit this screen select "Close"
 Slide 4 image. See text below.
  • If you choose to use the web site to get your meteorological data you will need to select "Meteorology and Solar Energy"
 Slide 5 image. See text below.
  • After selecting "Meteorology and Solar Energy" you will see the option of "Meteorology and Solar Energy" under Data Retrieval, select the method you wish to use to seach the database
 slide 6 image. See text below.
  • To access the data you will need to register with NASA Langley SSE. Registration is free and requires only minimal information
 Slide 7 image. See text below.
  • After registering you will see this screen if you selected to search by latitude and longitude otherwise a global map will appear for you to make your location selection
  • After entering a location (either by Latitude and Longitude or by graphic selection) a form will appear for you to select the data you are interested in obtaining.
  • You will have the choice of learning the definition or the Values for the data you have selected.
  • In order to get the numbers you need to enter into TANKS you have to select "Values" for "Parameters for Solar Cooking - Average insulation" and "Meteorology (Wind) - Wind Speed", Pressure, air temperature
  • For wind speeds select the "Wind Speed at 10 m for terrain similar to airports"
  • To get the Maximum and Minimum temperatures you can go to the Environment Canada Green Lane ( and follow this path: Weather > Climate Data > Climate Normals > Province Selection > Town Selection
  • Note the units from both websites are Metric and TANKS requires Imperial
  • After entering the meteorological data you can go directly into you emission estimations by entering a new tank record
  • To enter a new tank record choose one of the tank options along the top menu bar:
    • HFRT: Horizontal Floating Roof Tank
    • VRFT: Vertical Floating Roof Tank
    • IFRT: Internal Floating Roof Tank
    • EFRT: External Floating Roof Tank
    • DEFRT: Domed External Floating Roof Tank
  • For information on these tanks type go to Chapter 7 "Organic Liquid Storage Tanks" in the US EPA's AP-42 document :
 Slide 10 image. See text below.
  • If you have previously entered the meteorological data into the TANKS database you can go directly to "Create a New Tank Record"
  • To do this instead of selecting "Cancel" you would select "Create a New Tank Record" and press "OK"
  • After you have created the tank record it will appear in the "Open an Existing Tank Record" and can be accessed directly from this screen as well.
 slide 11 image. See text below.
  • After selecting "Create a New Tank Record" this screen will appear
  • Enter an identification number or name that is accurate, meaningful and unlikely to change
  • The description, province, city, and company fields are optional but are useful if you are reporting for more than one facility.
 Slide 12 image. See text below.
  • After you have populated all the fields in the Identification tab move on to the Physical Characteristics tab
  • Then enter the physical parameters of the tank in the fields provided
  • Note the units the program uses and ensure you are using the correct units
 Slide 13 image. See text below.
  • After the physical characteristics have been entered move on to the Site Selection tab
  • To use this screen you will have first needed to add your city to the meteorological database
  • Then select your city from the picklist
  • The meteorological data will then automatically populate the cells below
 Slide 14 image. See text below.
  • Enter or define the substance being stored in the tank
  • You can add chemicals and mixture to the Chemical database in the same manner as the meteorological database
    • Again this must be done before entering a new tank record.
    • The chemical database is found in the same menu as the meteorological database.
 Slide 15 image. See text below.
  • Enter the name of the mixture and its throughput for the each month
  • The "Distribute Throughput" button will evenly distribute the annual throughput over the months
  • If only one mixture is stored in the tank over the year use the "Fill Mixture Name With First Mixture Name" button
 Slide 16 image. See text below.
  • Before running the report save the record by selecting "Save"
  • After you have saved the record select "Run Report"
  • On this screen you will need to select what type of report you are interested in running (Brief, Summary or Detail)
  • Then you will need to select the time basis (Annual or Monthly)
  • If you select monthly you will need to select the months you are interested in.
  • Once you have made all the selections hit "OK" to run.
 Slide 17 image. See text below.
  • After running the report you will be asked to select a print style for the report.
  • You can print to your screen, printer, or to a file.
  • Since a record of all NPRI calculation needs to be kept for 3 years it is recommended to print to either a file or printer and then make sure the report isn't lost or misplaced.
  • TANKS report output is in pounds (lbs)

** Remember to watch your units, you will need to convert from Metric to Imperial to run TANKS then back to Metric for reporting to the NPRI.

  • If you decide to store your information in electronic format then choose print to file.
    • It doesn't matter which report style you have chosen (brief, summary or detail) the resultant file is the same for all three reports.
    • The default location to save the file is Program files > TANKS 4.0, however you can change the location by using the Browse function when asked for the Export file name
    • It is recommended to save the file as an Excel file, which will allow you to work with the releases generated by the TANKS program
