World Data Service for Paleoklimatologi administrerer International Tree-Ring Data Bank (ITRDB), verdens største offentlige arkiv af træringdata.  Tilsyn varetages af ITRDB's rådgivende udvalg . ITRDB inkluderer rå ringbredde, trætæthed, isotopmålinger og stedsvækstindekskronologier fra mere end 5.000 steder på seks kontinenter. Rekonstruerede klimaparametre er også tilgængelige for nogle områder.

Dendrokronologi studerer de årligt varierende ringbredder i træ. Træringmønstre i træ fra kulturarven indeholder unikke informationer om tidligere kronologi, samfundsøkonomi, det historiske landskab og dets anvendelser, klima og træteknologi. DCCD er et digitalt depot og interaktivt bibliotek af træringdata. Dens indhold er udviklet gennem forskning af blandt andet: arkæologiske steder (herunder gamle landskaber), skibsvrag, bygninger, møbler, malerier, skulpturer og musikinstrumenter. DCCD er baseret på Tree-Ring Data Standard (TRiDaS) og giver mulighed for konvertering af andre udbredte dataformater. Den indeholder digitale træring-måleserier og gennemsnitlige kronologier samt deres beskrivende og fortolkende metadata. Det giver bidragydere mulighed for at kontrollere og administrere adgangen til deres data.

​Den Internationale Multiproxy Paleofire Database (IMPD) er et arkiv af brandhistoriedata, der stammer fra naturlige proxyer, såsom træar og kul- og sedimentregistreringer. IMPD blev etableret med vejledning fra et rådgivende udvalg for at give et permanent depot for højkvalitets palæofildeposter fra hele verden. For mere information om paleofire-data, se vores Introduktion til Brandhistorie Rekonstruktion .

Vi er nationens (USA) førende autoritet for miljødata og administrerer et af de største arkiver for atmosfærisk, kystnær, geofysisk og oceanisk forskning i verden. NCEI bidrager til NESDIS-missionen ved at udvikle nye produkter og tjenester, der spænder over de videnskabelige discipliner og muliggør bedre dataopdagelse. 

Denne online ordliste er tilpasset fra Multilingual Glossary of Dendrochronology (1995). Den indeholder definitionen og oversættelsen af 351 udtryk på 7 sprog: engelsk, tysk, fransk, spansk, italiensk, portugisisk og russisk.

Monitoring Trends in Burn Severity (MTBS) er et multiagenturprogram designet til konsekvent at kortlægge forbrændingsgraden og omkredsen af brande på tværs af alle lande i USA fra 1984 og derefter.

​Paleoklimatologiske data stammer fra naturlige kilder såsom træringe, iskerner, koraller, stalagmitter og hav- og søsedimenter. Disse proxy-klimadata udvider vejr- og klimainformationsarkivet med hundreder til millioner af år. Dataene omfatter geofysiske eller biologiske måletidsserier og nogle rekonstruerede klimavariabler såsom temperatur og nedbør. Forskere bruger palæoklimatologiske data og information til at forstå naturlig klimavariation og fremtidige klimaændringer.

​OldList er en database med gamle træer. Dens formål er at identificere den maksimale alder, som forskellige arter på forskellige lokaliteter kan opnå, således at usædvanligt høje individer anerkendes. Ud over denne originale OldList opretholder Neil Pederson ved Harvard Forest og kolleger ved Virginia Tech Tree Program en følgesvend Eastern OldList , der fokuserer på gamle træer, der vokser i det østlige USA.

Eastern OLDLIST er en 'franchise'-database over OLDLIST , en database over gamle træer og deres aldre. Formålet med denne liste er at identificere og fremhæve maksimal alder for arter i det østlige Nordamerika. Denne liste vil kun indeholde velverificerede eller veldokumenterede træaldre (se Teknisk information nedenfor for yderligere information).

Velkommen til Gymnosperm-databasen, nettets førende kilde til information om nåletræer og deres allierede. Siden vi gik online i 1997, har databasen tiltrukket sig verdensomspændende opmærksomhed som en let tilgængelig, videnskabeligt nøjagtig kilde til information om klassificering, beskrivelse, økologi og anvendelser af denne kulturelt og økologisk vigtige plantegruppe.

Denne database over dendrokonologisk relevante plantearter indeholder i øjeblikket navnene på 1.166 træ- og buskarter, for hvilke træringe er blevet analyseret i den publicerede litteratur. Databasen giver ITRDB-koder for træarter.

Følgende oplysninger er givet for hver art eller sort: Latinsk navn og myndighed, almindelige navn(e) på engelsk og/eller lokale ikke-europæiske navne. For ca. syv hundrede arter med træringdata og kronologier tilgængelige i International Tree-Ring Data Bank ( ITRDB ), yderligere information omfatter:

• Crossdating Index (CDI), hvor

  • "0" angiver, at arten ikke krydsdateres, eller ingen krydsdateringsinformation er tilgængelig

  • "1" angiver en art, der vides at krydse i og mellem træer (mindre betydning for dendrokronologi)

  • "2" angiver en art, der vides at krydsdatere på tværs af en region (stor betydning for dendrokronologi).

*Bemærk venligst, at fra den 17. februar 2022 var databasen ikke blevet opdateret siden 2013.

The Tree Mortality Network is an initiative of the IUFRO task force on tree mortality. Our mission is to facilitate collaboration between scientists to combine expertise, knowledge and data, thereby allowing a global assessment of tree mortality and providing crucial information for forest managers and policymaking.

The European Atlas of Forest Tree Species is the first comprehensive publication of such a unique and essential environmental resource, that is, our trees. Leading scientists and forestry professionals have contributed in the many stages of the production of this atlas, through the collection of ground data on the location of tree species, elaboration of the distribution and suitability maps, production of the photographic material and compilation of the different chapters.

The main European added value of the ESBN has been the joint effort towards bringing together soil information collected in separate European countries, using very different methodologies, standards and scientific backgrounds, into one single geographic information system (GIS) while demonstrating that, at least for soil science, a “Europe without borders” is possible. Lengthy cross-border harmonisation sessions between bordering countries have resulted in a common fully harmonised soil geographical database of Europe at a nominal scale of 1:1,000,000. This database has allowed the production of the maps that are at the heart of the new “Soil Atlas of Europe".
