d

struct

The variable containing the data. The data may be as a single variable, a vector or an array. d structure contains the following fields:

• Station_codename – Code name of the station
• Measurements – Number of measurements or sample collection in the field. Structure containing the following fields:
• Date – Time of measured parameter/sample collection
• Tests– Number of test performed/ measured parameters. Structure containing the following fields:
• Test_name_id – Id of measured parameter/test
• Result – Result of measured parameter/test
• Result_duplicate (optional) – Quality assurance check
• Stage (optional)– Stage of monitoring
• Measurement_method (optional) – Method of measurement

dDescription

cell

Description of the fields of ‘d’ variable. A cell contains two columns: the first contains the name of the field/column of data, the second contains a description of them. All data must be specified.

Description

char

The text description of the data contained in the file

FormatName

char

Name of data format MDDF (Multi Dimensional Data Format).

FormatVersion

real

When changing/expansion of the format change its version. It can have one number after the decimal point.

TestParameters

struct

The variable containing the parameters of data. The data may be as a single variable, a vector or an array. TestParameters structure contains the following fields:

• Test_name – Name of test/measured parameter
• Unit – Unit of test/measured parameter
• Type – Data type number:

An array contains two columns: the first contains the name of the field/column of data, the second contains the data type number. All data must be specified. The Numbers of Data type:

1 – the real data without limits,

2 – the integer data,

3 – text value,

4 – the real number rounded to 0.1 (shown as 11),

5 – time in Matlab format serial time – the time display format; seconds with accuracy 1/10,

6 – the real data display in an engineering manner with one decimal place, e.g.: 3.5E6, (obsolete, recommended 2cd)

7 – the real data display in an engineering manner with two decimal place, (obsolete, recommended 2cd)

bc – (b and c are code digits) the real data is displayed in fix-point manner with at minimum b places before decimal and c decimal place,

                e.g. For number 3.149.

                10:          „3”

                11:          „3.1”

                12:          „3.15”

                20:          „03”

                23:          „03.149”

1bc– the same manner as bc, but with place for a sign (space for sign „+”, sign ‘-’ for sign „-”),

2cd– (c and d are code digits), the real data is displayed in an engineering manner, with place for a sign (space for sign „+”, sign ‘-’ for sign „-”), with c decimal place and exponent expressed by d places. The sign in exponent is always displayed.

• Technique (optional) – Technique
• LOD (optional)– Limit of detection (Lower and Upper)
• LODType (optional)– Data type number of LOD
• Accreditation (optional) – Accreditation body
