Site Criteria

Latitude

Only sites with latitudes within the range [South, North] will be selected. Use positive values for the Northern Hemisphere and negative values for the Southern Hemisphere. The default values show the range of latitudes available in the database. These values cannot be blank.

Longitude

Only sites with longitudes within the range [West, East] will be selected. Use positive values for the Eastern Hemisphere and negative values for the Western Hemisphere. Use the center on Date Line option if your area of interest straddles the Date Line. The default values show the range of longitudes available in the database. These values cannot be blank.

Terrain

Only sites which have the specified terrain types will be selected. The orographic option will include sites for which there may be an orographic influence on rainfall.

Identifier

Only sites with the specified identifiers (see the site catalog) will be selected. Multiple identifiers should be separated with a space.

Rain Criteria

Timestamp

Only records with timestamps in the range [Begin, End) will be selected. The default values show the range of timestamps available in the database. These values cannot be blank.

Last Modified

Only records which have been added to the database or modifed on or after this date will be selected. The default value is the earliest date available in the database, or the date of your last query if you had used the remember me option (see below). This value cannot be blank.

Output Options

Format

Data will be compressed using the selected format. Each database record has a unique identifier and a timestamp indicating when that record was last modified. Some records also have footnotes. These data will be included in your output if you select the include metadata option.

E-mail Address

When the query is complete a notification will be sent to this e-mail address. If the remember me option is selected this e-mail address and the date of your last query (see above) will automatically be filled in during subsequent queries. This value cannot be blank.
