And there it is: green-up on West Chena Ridge in Fairbanks, four days earlier than the 50 year median, and first "earlier than median" green-up since 2019.

@AlaskaWx @CarrieinFbx @debmcqueen @leahwrenn @leepetersen @anisian @kenrhill Two Rivers is lagging a touch behind, but that’s OK. I’m glad I’ll be home to see when it hits our yard.

If midsummer is on or around the solstice then this is the beginning of summer.

I remember last year feeling like the solstice actually being the midpoint of the season made so much more sense to my sense of being in my environment than the astronomical seasons did. Summer beginning now also feels far more accurate to me.

Green-up in Fairbanks is approaching. Using observed temperatures since March 1st and the forecasts for the ten days, our little model now showing a 60 percent of green-up late next week. The long term average green-up is May 8 and this year is sure to be earlier than that. @CarrieinFbx @anisian @mivox @themattphelps @debmcqueen @leepetersen @dboo @Climatologist49

@AlaskaWx @CarrieinFbx @anisian @themattphelps @debmcqueen @leepetersen @dboo @Climatologist49 I called May 3 in a friend’s post on Facebook. I expect everything here will look different when we get back from Missouri next weekend.

An article from today's Washington Post on how spring is arriving earlier.
And how we, as gardeners, are noticing it.

The Case For Remote Sensing Of Individual Plants

https://doi.org/10.1002/ajb2.1347 <-- shared short article

#GIS #spatial #mapping #UAV #drone #drones #LiDAR #photosynthesis #imagingspectroscopy #trees #plants #vegetation #forest #monitoring #identification #satellite #cubesat #landsurface #landcover #spatialanalysis # interpretation #biology #scale #sensor #technology #fieldwork #fieldplatforms #spatiotemporal #resources #naturalresources #phenology #photogrammetry #plantbiology #model #modeling #inference #remotesensing

aerial images - High-resolution images from the Planet Labs constellation of cube-sats detect flowering individual trees in the Peruvian Amazon (yellow objects in panel A) and Colombian Amazon (pink objects in panel B). Many thousands of flowering individuals are apparent across hundreds of kilometers of Amazonian forest in these flowering events. Scale bar = 500 m.
aerial and oblique remotesensing-created images - Drone remote sensing of individual trees. (A) Ultra-high-density drone lidar resolves individual tree structure in a temperate beech forest in the southern Czech Republic. Colors indicate elevation, and the tallest trees are about 40 m aboveground. Measurement density here is 4323 points per square meter. (B) High-spatial resolution optical remote sensing from a low-altitude drone in the Atlantic lowlands of Costa Rica. We used methods from computer vision to construct three-dimensional scene geometry from two-dimensional images. The image is a natural color composite. (C) Same area as B, but colored by surface elevation, where warmer colors indicate taller objects. A single Goethalsia meiantha crown is outlined in white. The area of this crown is 157.3 m2. At a pixel size of 1 cm, this crown contains 1.573 × 106 pixels, demonstrating the tremendous increase in measurement density at high-spatial resolution. Scale bar in B and C = 30 m.

This is an excellent @longreads article (or book excerpt rather) about #Thoreau and #Darwin (since today is Darwin's birth anniversary). It hits on so many of the major reasons why I love, and continue to be inspired by, Thoreau.

"[Thoreau] hovered between design and chance, between idealism and materialism. Which is why his argument in “The Succession of Forest Trees” is so remarkable—for Thoreau locates mystery and wonder within materialism."

"After a while I learn what my moods and seasons are. I would have nothing subtracted. I can imagine nothing added. My moods are thus periodical, not two days in my year alike. The perfect correspondence of Nature to man, so that he is at home in her!"

#ClimateDiary Once again i have to ask my perennial question here: what is normal? I just don’t know! Yet again having to acknowledge how unobservant and ignorant i am with regard to #Phenology. This time it’s trees srill having all their (now brown/orange, pretty overall) leaves. It’s almost December. Have they not normally dropped their leaves by now? I don’t know.

Just saw that our (already very scraggly looking) tree has suddenly started flowering - not everywhere, but around 4-5 flowers across the tree. It’s flowering season is normally May/June. Is it just ours or have others observed the same? Or is it normal for them and i just didn’t notice before?

charliestyr,

@pvonhellermannn there’s a bridleway near my work that always has a lovely swathe of crocus in spring - they have all come out over last few weeks. I can’t remember if that’s happened before - either way when I checked their flowering time it is meant to be spring from what I found….

@pvonhellermannn We moved into our house (Georgia, USA) in August last year, and our crabapple had fruit when we moved in, then suddenly bloomed a second time in Sept. It just did the same thing again this year. No idea if this is a weirdness of this particular tree or just climate weirding. The bees are of course delighted.
