Documenting Data Quality Ted Habermann, NOAA/NESDIS/NGDC Documentation: It’s not just discovery... 50% change in global average Why? i checked my archives, and here is what i found out: it appears that the current 3rd generation algorithm was implemented into operations around Oct-Nov 2002 time frame. cannot say more precisely, as all correspondence i am looking at, talks about this indirectly. (maybe it's what's referred to as the Phase II algorithm.) At the same time, we had implemented quite a few other changes fixing data bugs and formats: view angle problem, increased digitization in all channel's reflectances and AODs, etc. The jump is deemed due to introducing 3rd generation algorithm, which replaced the 2nd generation. The new numbers (~0.08) look more realistic than the previous ones (~0.05 or so). The changes seen in the data is close to the expected effect of this change. The 3rd gen alg takes into account the exact spectral response, whereas the 2nd gen is generic ("one size fits all"). hopefully this settles the issue..

XML Attributes: Objects and References ISO XML consists of tags, elements (with or without content), and attributes. An attribute is a name/value pair that exists within a start-tag or empty-element tag. Attributes provide additional information about an element which is not part of the data. Attribute values must contain either single or double quotes. This example shows a step element with one attribute, number with a value of “3”: Connect A to B. Many of the XML attributes used in the ISO Standards fall into two groups: identifiers and references: Identifiers: id and uuid References: uuidref and xlink:href Objects that start with upper case letters have identifiers (id and uuid) Roles that start with lower case letters have references (uuidref and xlink:href) object: CI_ResponsibleParty id="JaneDoe" object: CI_ResponsibleParty id="JohnDoe" role: friend xlink:href=#JohnDoerole: friend xlink:href=#JaneDoe
